Grad Student Kevin Fries earns NOAA Fellowship

Doctoral Student Kevin Fries recently received a Great Lakes Long-term Fellowship.| Short Read

The fellowship is administered by U-M’s Cooperative Institute for Limnology and Ecosystems Research (CILER) and funded by NOAA’s Great Lakes Environmental Research Lab (GLERL).

Fries is advised by Assistant Professor Branko Kerkez. His interests include large scale water systems, especially the Great Lakes.

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
