The Great Lakes serve as a living lab

On August 20, Alford and fellow Michigan faculty member Melissa Duhaime were two of more than 1,000 participants in the world’s largest simultaneous water sampling project for microplastics — tiny pieces of plastic that measure mere millimeters in size — as part of eXXpedition Great Lakes 2016.
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
