CEE Ph.D. Student Chen Feng (advised by Vineet Kamat) received an honorable mention at the Fall 2012 Mobile Apps Challenge. Feng’s mobile application named MARvigator is a navigation app for Android that utilizes augmented reality technology for indoor localization and way-finding in unfamiliar environments. The Mobile Apps Challenge promoted entrepreneurial thinking and encouraged the U-M developer community to create innovative mobile designs. U-M students, faculty, and staff submitted a diverse collection of medical apps, games, educational apps, plus apps relating to health and lifestyle. More information can be found here

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
