David Berry receives 2010 CH2M Hill/AEESP Outstanding Doctoral Dissertation Award

Recent PhD graduate, David Berry (advisor: Lutgarde Raskin) was selected as one of two recipients of the 2010 CH2M Hill/AEESP Outstanding Doctoral Dissertation Award.| Short Read

This award annually recognizes two outstanding doctoral dissertations that contribute to the advancement of environmental science and engineering, and is considered a top honor for recent graduates. Please join us in congratulating David on this honor. For more information on Professor Raskin’s research group: http://www.sitemaker.umich.edu/raskinlab/home

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
