2017 Van Vlack Lecture featuring Cal University Professor Ramamoorthy Ramesh

In the 2017 Van Vlack Lecture, Ramamoorthy Ramesh will use Energy as a “Clear and Present” example of where we, as scientists, engineers, young and not-so-young, need to rise up and meet the challenges that we are faced with.| Short Read
The Van Vlack Lecture Series was established in honor of L. H. Van Vlack, to provide a distinguished lecture series from the outstanding leaders in the field of Materials Science and 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
