Another CLASP doctoral student has successfully defended her dissertation. Congratulations, Dr. Petersen!

Dr. Alicia Petersen

Defense Date: 5/4/2020

Dissertation Title: Space Weather Propagation in the Inner Heliosphere

Faculty Advisors: Prof. Michael Liemohn and Assoc. Prof. Susan Lepri.

Dr. Petersen plans to take the summer off to spend maternity leave with her newborn son, who is due in just a few weeks. She plans to return to research this fall at the Air Force Research Laboratory working with Dr. Stephen Kahler in Albuquerque, NM. She is now living full-time with her husband, an aerospace engineer, in Albuquerque, NM, the Land of Enchantment.

Congratulations, Dr. Petersen

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
