Professor Katopodes receives Chi Epsilon Excellence in Teaching Award

Professor Nikolaos D. Katopodes was selected to receive the 2008-2009 Chi Epsilon Excellence in Teaching Award for the Great Lakes District. | Short Read

He was nominated by the Department of Civil and Environmental Engineering (CEE) Chi Epsilon student chapter for his dedication to teaching. Educating students is the primary mission of an academic, and Professor Katopodes’ commitment to student learning leaves an important mark on CEE alumni.

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
