Jongho Kim selected as a recipient of the Rackham International Student Fellowship

CEE graduate student, Jongho Kim, was selected as a recipient of the Rackham International Student Fellowship.| Short Read

The Fellowship assists outstanding international students, particularly those who may be ineligible for other kinds of support because of citizenship. Students are nominated by their department or program of study and selection criteria for candidates include: strong academic record, making good progress toward the degree, and demonstrate outstanding academic and professional promise.

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
