Four students receive international fellowships

Rackham graduate school recently selected four CEE students to receive international fellowships.| Short Read

Yong Xiao and Yinyin Ye were selected for the Rackham International Student Fellowship, which assists outstanding international students, particularly those who may be ineligible for other kinds of support because of citizenship. Professor Vineet Kamat advises Xiao and Assistant Professor Krista Wigginton advises Ye.

Pin Hsuan Chang and Tung-Yu Wu were awarded the Chia-Lun Lo Fellowship, which assists outstanding students in Rackham programs who have earned a previous degree from a university in Taiwan. Chang is co-advised by Wigginton and Associate Professor Terese Olson. Wu is advised by Professor Sherif El-Tawil.

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
