Four graduate students earn NSF fellowships

The National Science Foundation (NSF) has selected four CEE doctoral students to receive a 2016 NSF Graduate Research Fellowship Program (GRFP) Fellowship.| Short Read

The awardees are Julie Bateman, Emily Crossette, Katherine Flanigan and Sara Troutman.

The GRFP recognizes and supports outstanding graduate students who are pursuing research-based master’s and doctoral degrees in science, technology, engineering, and mathematics (STEM) and in STEM education. The GRFP provides three years of support for the graduate education of individuals who have demonstrated their potential for significant research achievements in STEM and STEM education.

Bateman is advised by Associate Professor Dimitrios Zekkos; Crosette is advised by Professor Lutgarde Raskin and Assistant Professor Krista Rule Wigginton; Flanigan is advised by Professor Jerry Lynch and Troutman is advised by Assistant Professor Branko Kerkez and Professor Nancy Love.

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
