Joe Griffin Eisley, a beloved teacher to his many students, dies at 92

Joe Griffin Eisley spent 14 years as an Associate Dean in the College of Engineering. During this time, he was involved in revising the engineering curriculum and in developing programs to encourage women and minorities to study engineering. His proudest accomplishment at the university, however, was to see so many of his former students succeed in their engineering careers.
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
