Freelance journalist Scot Woods interviews Alec Gallimore, the Robert J. Vlasic Dean of Engineering, and Scott Hall, a research engineer at NASA Glenn in Cleveland, OH, about how they came to work on plasma-based engines for space missions, how the X3 thruster works, and the possibilities it offers for NASA and human space exploration.

The new podcast, called “The High Five,” celebrates Michigan success stories.

Listen to The High Five Episode 2: The X3 Thruster on Soundcloud.

Dean Gallimore is also the Richard F. and Eleanor A. Towner Professor, an Arthur F. Thurnau Professor, and a professor of aerospace engineering.

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
