Avish Kosari, a graduate student in the Electrical Engineering program, received a Rackham International Student Fellowship to continue her studies as a doctoral student in Prof. David Wentzloff‘s research group.

In her first directed study project with Prof. Wentzloff, Avish is currently conducting research on ultra-low power radio technology and designing a low-power RF power amplifier. Power amplifers are the most power-hungry components in a radio transceiver. The device has applications in miniature-scale biomedical monitoring systems that need to operate for extended times without being recharged.

Ms. Kosari received her bachelor’s degree from Shahid Beheshti University, Tehran, in 2010.

The Rackham International Student Fellowship assists outstanding international students, particularly those who may be ineligible for other kinds of support because of citizenship. To be eligible, international graduate students must have successfully completed one year of graduate study as a master’s or precandidate student. Nominees must have a strong academic record, be 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
