Kemper Publishes in Nature Communications - 2017.1.14

Professor Lex Kemper and colleagues at the Max Planck Institute for the Structure and Dynamics of Matter have demonstrated how laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales. Their work is published in Nature Communications.

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity to observe particle properties that have no realization in elementary particles. In the present study, first principle calculations are used to predict how laser light can be used to create Weyl fermion states in 3D Dirac materials and to switch between Weyl semimetal, Dirac semimetal and topological insulator states on ultrafast timescales.

This year 391 scientists received this honor.

Blondin, Alumni Distinguished Undergraduate Professor of Physics and Associate Dean for Research in the College of Sciences, was elected for distinguished contributions to astrophysics and physics education, particularly in supernovae and supernova remnants.

Ade Group develops novel solar cell fabrication 2016.11.29

Professor Harald Ade's group have developed a new strategy for fabricating more efficient plastic solar cells. The work has implications for developing solar cells with a wider absorption range and increased efficiency. Masoud Ghasemi, a graduate student in physics at NC State and lead author of a paper describing the research, worked with a team of other NC State physicists led by Harald Ade and chemists from the University of North Carolina at Chapel Hill led by Wei You to identify a way to solve the production problem. “Using thermodynamic techniques, we were able to find that this particular mixture was undergoing ‘alloying,’ in which the donor polymers tend to group up together and push the fullerene away,” Ghasemi says. “This explains why so many conventionally produced ternary cells may have low efficiency.” The team decided to solve the alloying problem by mixing each polymer separately with the fullerene, rather than mixing all three materials together at once. They created two distinct mixtures which were layered onto the substrate, creating sequentially cast ternary (SeCaT) solar cells, which did not fall prey to alloying.

Ade Group and Collaborators Achieve Solar Cell Record - 2014.11.28

The NC State physics group of professor Harald Ade and researchers from Hong Kong University of Science and Technology have found that temperature-controlled aggregation in a family of new semi-conducting polymers is the key to creating highly efficient organic solar cells that can be mass produced more cheaply. Their findings also open the door to experimentation with different chemical mixtures that comprise the active layers of the cells.

In a paper published in Nature Communications, Ade, Ma and a team of chemists from the Hong Kong University of Science and Technology led by He Yan show that size scale and aggregation within these devices are strongly temperature dependent. They also show that record efficiencies of up to 10.8 percent - as opposed to the currently published 9.8 percent - are achievable with the substitution of numerous fullerenes. Additionally, this performance can be achieved in thick film devices.

"Once we saw how temperature affected the aggregation and morphology of these solar cells, it allowed the chemists more freedom to play with different chemical compositions in the active layer," Ade says. "Yan's team demonstrated 10 percent efficiency with 10different mixtures, and in thicker films. So these solar cells could be compatible with existing methods of mass production, like slot die casting and roll-to-roll processing similar to newspaper printing, rather than the more expensive production methods currently in use that are required for thickness control.

Jiuyang Wang received his Ph.D. at the May 2014 graduation ceremony.

Hubble Fellow Coming to NC State- 2014.5.2

Evan O'Connor has received one of 17 Hubble Fellowships from NASA, and will be bringing his fellowship to NC State to work with faculty in the astrophysics group on core-collapse supernovae. Evan will be coming to Raleigh from the Canadian Institute for Theoretical Astrophysics (coincidently he is a native of Prince Edward Island). He obtained his Ph.D. from CalTech in 2012 where he developed computational methods for relativistic astrophysical systems.

Complementary to observations of the exteriors of progenitors of core-collapse supernovae are observations that probe the interior of massive stars at the end of their lives. One potential channel available to probe the interior structure of stars at the epoch of core collapse is direct observations of core-collapse supernova neutrinos, gravitational waves, and nucleosynthetic yields. At NC State, Evan will use the results of multi-dimensional neutrino-radiation-hydrodynamic simulations of core collapse to explore the connection between these observables and the interior structure of core collapse progenitors with the goal of constraining stellar evolution with the next galactic core-collapse supernova.

The Hubble Fellowship Program supports outstanding postdoctoral scientists whose research is broadly related to NASA Cosmic Origins scientific goals as addressed by any of the missions in that program: the Herschel Space Observatory, Hubble Space Telescope (HST), James Webb Space Telescope (JWST), Stratospheric Observatory for Infrared Astronomy (SOFIA), and the Spitzer Space Telescope.

Her poster on Investigating the Dynamics of a Folded Polymer Tube describes her work over the past year in Professor Karen Daniels lab.

Ade Group Publishes in Nature Photonics - 2014.4.7

Former NC State postdoc John Tumbleston and collaborators from the Ade research group and from UNC-Chapel Hill published a paper April 6 in Nature Photonics, The influence of molecular orientation on organic bulk heterojunction solar cells.

New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the design and manufacture of more efficient and economically viable organic solar cell technology.

Organic solar cell efficiency depends upon the ease with which an exciton – the energy particle created when light is absorbed by the material – can find the interface between the donor and acceptor molecules within the cell. At the interface, the exciton is converted into charges that travel to the electrodes, creating power. While this sounds straightforward enough, the reality is that molecules within the donor and acceptor layers can mix, cluster into domains, or both, leading to variances in domain purity and size which can affect the power conversion process. Moreover, the donor and acceptor molecules have different shapes, and the way they are oriented relative to one another matters. This complexity makes it very difficult to measure the important characteristics of their structure.

NC State physicist Harald Ade, UNC-Chapel Hill chemist Wei You and collaborators from both institutions studied the molecular composition of solar cells in order to determine what aspects of the structures have the most impact on efficiency. In this project the team used advanced soft X-ray techniques to describe the orientation of molecules within the donor and acceptor materials. By manipulating this orientation in different solar cell polymers, they were able to show that a face-on alignment between donor and acceptor was much more efficient in generating power than an edge-on alignment.

"A face-on orientation is thought to allow favorable interactions for charge transfer and inhibit recombination, or charge loss, in organic solar cells," Ade says, "though precisely what happens on the molecular level is still unclear."

NuSTAR Satellite Reveals Supernova Structure - 2014.4.2

A new and powerful satellite has given researchers a way to see into the dark interiors of supernovae. Their observations of the supernova remnant Cassiopeia A shed more light on the mechanics of these explosions.

"The new Cas A images give us new information about not only the elements that are created in a supernova, but the structure of these giant explosions," says Stephen Reynolds, NC State astrophysicist, member of a team of scientists helping interpret data collected by the NuSTAR satellite and co-author of a paper describing the research. "These data will help us refine our models of these explosions to be more consistent with what actually happens when a star explodes."

Researchers from the California Institute of Technology developed NuSTAR (Nuclear Spectroscopic Telescope ARray), the first X-ray satellite capable of making true images of more energetic, or "harder" X-rays, including those produced by radioactive titanium. Unlike the X-rays described above, which show material that is hot, radioactive titanium glows in X-rays no matter what, making it visible wherever it is. In a paper published today in Nature, CalTech and Berkeley researchers detail their findings from Cas A.

Physics majors awarded NSF Graduate Research Fellowships- 2014.4.2

The National Science Foundation (NSF) has announced this year's recipients of Graduate Research Fellowships (GRF), which includes three students from the NC State Physics program: Khalida Hendricks, Alex Mauney, and Anne Watson. The 2013 GRF class included NC State Physics alumni Mary Burkey and Adam Keith.

Since 1952 (Wes Doggett received a GRF in that first year!), NSF has provided fellowships to individuals selected early in their graduate careers based on their demonstrated potential for significant achievements in science and engineering. With its emphasis on support of individuals, GRFP offers fellowship awards directly to graduate students selected through a national competition. The GRFP provides three years of financial support within a five-year fellowship period for graduate study that leads to a research-based master's or doctoral degree.

Ade Group Publishes in Advanced Materials- 2014.3.28

Research from Harald Ade's group reveals that solar cell efficiency is based upon a delicate balance between the size and purity of the interior layers, or domains. These findings may lead to better designs and improved performance in organic solar cells.

Polymer-based solar cells are intended to have two domains, consisting of an electron acceptor and an electron donor material. Solar cell efficiency is based upon several factors: the ease with which excitons (the energy particles created by solar cells when light is absorbed) can travel to the interface of the donor and acceptor domains while retaining as much of the light’s energy as possible; and, once the charges are separated from the excitons, how efficiently separated charges travel to the device electrodes for collection.

In reality, however, these domains are not separate and pure, and there can end up being many more than two. Current processing methods create a complex, multi-domain structure, which impacts all of the factors involved in the solar cell’s efficiency.

NC State physicist Harald Ade and collaborators wanted to find out exactly how the solar cell’s complex structure impacts its performance. Using advanced soft X-ray techniques, Ade and colleagues from the Chinese Academy of Sciences found that the domains mixed in unusual and sometimes contradictory ways.

The paper, titled "Quantification of Nano- and Mesoscale Phase Separation and Relation to Donor and Acceptor Quantum Efficiency, Jsc, and FF in Polymer:Fullerene Solar Cells," appears in Advanced Materials.

Mia de los Reyes named Goldwater Scholar - 2014.3.21

Mia de los Reyes, a physics and mathematics double major at NC State University, was named a 2014 Goldwater Scholar. She is one of three Goldwater Scholars from NC State this year.

Alwin Mao was also named a Goldwater Scholar. Alwin is a UC-Berkely student who participated with Mia in the NC State Undergraduate Research in Computational Astrophysics program during the summer of 2012.

The Barry Goldwater Scholarship and Excellence in Education Program was established by Congress in 1986 to honor Senator Barry Goldwater, who served his country for 56 years as a soldier and statesman, including 30 years of service in the U.S. Senate.

The purpose of the Foundation is to provide a continuing source of highly qualified scientists, mathematicians, and engineers by awarding scholarships to college students who intend to pursue research careers in these fields. This year's Goldwater Scholars were selected on the basis of academic merit from a field of 1,166 mathematics, science, and engineering students who were nominated by the faculties of colleges and universities nationwide. Each institution is allowed to submit up to four nominations.

Previous NC State Physics majors who have received the Goldwater Scholarship include Cody Melton, Derek Justice, Justin Brockman, and Patrick Bowen.

Dean Lee describes shape of oxygen 16 - 2014.3.13

Oxygen-16, one of the key elements of life on earth, is produced by a series of reactions inside of red giant stars. Now a team of physicists, including one from North Carolina State University, has revealed how the element’s nuclear shape changes depending on its state, even though other attributes such as spin and parity don’t appear to differ. Their findings may shed light on how oxygen is produced.

Carbon and oxygen are formed when helium burns inside of red giant stars. Carbon-12 forms when three helium-4 nuclei combine in a very specific way (called the triple alpha process), and oxygen-16 is the combination of a carbon-12 and another helium-4 nucleus.

Although physicists knew what oxygen-16 was made of, they were still puzzled by the fact that both the ground and first excited states of the element had zero spin and positive parity. A similar situation occurs in carbon-12 with the ground state and second zero-spin state known as the Hoyle state. At room temperature, only the ground state of oxygen-16 is seen due to the very cold temperature compared to nuclear energies. But the excited states of oxygen-16 become important for the helium-burning reactions inside stars.

Lee, with colleagues Evgeny Epelbaum, Hermann Krebs, Timo Laehde, and Ulf-G. Meissner, had previously developed a new method for describing all the possible ways that protons and neutrons can bind with one another inside nuclei such as carbon-12 and the Hoyle state. They used an approach called “effective field theory” formulated on a complex numerical lattice that allows the researchers to run simulations that show how particles interact, and so reveal the structure of the nuclei.

In this work, the same team plus Mississippi State physicist Gautam Rupak, found their lattice revealed that although both the ground and first excited states of oxygen-16 “look” the same in terms of spin and parity, they are in fact quite different structurally. In the ground state, the protons and neutrons are arranged in a tetrahedral configuration of four alpha clusters containing two protons and two neutrons each. For the first excited state, the alpha clusters are arranged in a square.

The results appear online March 12 in Physical Review Letters.

Carla Frölich named Cottrell Scholar - 2014.2.28

Dr. Carla Fröhlich, assistant professor in the Department of Physics, has been named a 2014 Cottrell Scholar by the Research Corporation for Scientific Advancement (RCSA) for her proposal, “The Origin of the Heaviest Nuclei in the Universe.”

The Cottrell Scholar program only accepts 10 percent of applicants; its award winners are elite chemists and physicists from around the country. The main goal of the program is to promote and support the university scholar model in which faculty members consistently demonstrate excellent research programs and innovative approaches to student learning at the undergraduate level.

Fröhlich’s research interests lie in theoretical nuclear astrophysics, focusing on the origin of the elements. Her work includes studying core collapse supernovae as nucleosynthesis site, identifying critical nuclear and neutrino physics for nucleosynthesis, abundances in metal-poor halo stars, and the origin of the elements heavier than iron. Her main contributions are the discovery of a new nucleosynthesis process, the Neutrino p-Process, which for the first time allows explanation for the observed abundances in the most metal-poor stars, and the prediction of neutron star mass and nickel yields from core collapse supernova simulations.
