James Duderstadt wins medal

The American Society of Mechanical Engineers has awarded James Duderstadt, president emeritus of U-M and University Professor of Science and Engineering the 2016 Ralph Coats Roe Medal, which honors those who have advanced the public appreciation for engineers.| Short Read

The award committee cited his “outstanding public service as a professor and university administrator; for leadership roles in defining the science and technology agenda for the nation: and for efforts to grow underrepresented groups in our educational institutions.”

Duderstadt will give a lecture at the annual meeting of the American Society of Mechanical Engineers. Previous winners include great engineers in industry and academia, members of Congress, and great popularizers of science such as Carl Sagan and Bill Nye.

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
