Ms. Courtney Peckens, was selected for honorable mention for the Ford Foundation Fellowship Program 2012 Dissertation Competition. She is advised by Jerry Lynch. Congratulations to Courtney for being selected for honorable mention. This is a highly competitive program and attests to the high quality of her application and our graduate students.

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
