The US Secretary of Energy appointed Kimberlee Kearfott, professor of NERS, to the Environmental Management Advisory Board. These site-specific boards advise and make recommendations on issues such as environmental restoration, waste management, disposal of non-stockpile nuclear materials, among other issues facing sites where nuclear and radiological research is carried out.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
