DOE provides the majority (approximately 90%) of federal support
for high-energy and nuclear physics research, which uses advanced accelerator
facilities as well as detectors placed underground and in space to understand
the fundamental nature of matter, energy, space, time and the properties and
interactions of atomic nuclei and nuclear matter.
Scientists at the Department of Energy's Oak Ridge National Laboratory used ultrafast laser spectroscopy at the Center for Nanophase Materials Sciences to demystify the dynamics of the negative trions. They explored the behavior of the charged quasiparticle in a two-dimensional semiconductor that is an excellent absorber of sunlight. Their insights, published in the journal Physical Review B, may prove important for advancing technologies for solar energy and quantum computing.
The inaugural American Physical Society (APS) Division of Particles and Fields Instrumentation Award has been presented jointly to David Nygren of the University of Texas at Arlington and Veljko Radeka of the US Department of Energy's Brookhaven National Laboratory. Nygren and Radeka received the award during the APS 'New Technologies for Discovery' Workshop on Oct. 5, 2015, at the University of Texas at Arlington.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
