CEE Student Sean Murphy named Dow Fellow

Graduate Student Sean Murphy is one of forty students who were recently named Dow Sustainability Fellows.| Short Read

The new fellows were selected from a distinguished group of nominees from 11 programs across the campus. Each school or college was asked to nominate up to 10 candidates, and this group marks the third cohort of Dow Sustainability Master’s/Professional Fellows at the university. These fellows will become part of a growing collaborative community of scholars focused on interdisciplinary approaches to a broad array of sustainability challenges.

Murphy is an MSE student in Environmental Engineering. He is co-advised by Professors Lutgarde Raskin and Nancy Love.

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
