Andrew Tadd, a lecturer in the Department of Chemical Engineering, is the College of Engineering’s 2017-18 Thomas M. Sawyer, Jr. Teaching Award recipient. The award honors non tenure-track faculty who have demonstrated sustained excellence in instruction and guidance at the undergraduate levels.

Tadd received his PhD in chemical engineering from U-M in 2006 and continued as a postdoctoral fellow before joining the department’s staff in 2007 as an assistant research scientist. In recent years, he has taught ChE 343, Separation Processes; ChE 431, Engineering Statistics and Problem Solving; and the senior design course, ChE 487.

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
