We’re very pleased to report that another Climate & Space student has successful defended his doctoral dissertation!

Dr. Benjamin Alterman

Defense Date: 10/11/2019

Dissertation Title: The Significance of Proton Beams in the Multiscale Solar Wind

Faculty Advisor: Prof. Justin C. Kasper

Dr. Alterman will continue to work with Prof. Kasper on Wind Faraday Cup data, as well as data from the Parker Solar Probe mission here at U-M. His long-term plans include joining the Southwest Research Institute (SwRI) in San Antonio, TX to work with CLASP Research Prof. Stefano Livi and SwRI faculty member Dr. Mihir Desai on a variety of heliospheric missions.

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
