CEE researchers featured in SSRL news

The Stanford Synchrotron Radiation Lightsource (SSRL) Headline News recently featured the work of doctoral student Yuqiang Bi and Professor Kim Hayes.| Short Read

Their paper, “Nanoparticulate FeS as an Effective Redox Buffer to Prevent Uraninite (UO2) Oxidation,” was listed as a science highlight. The abstract states: “This study may help evaluate the long-term stability of uranium contaminations in the subsurface.”

Please join CEE in congratulating Bi and Hayes!

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
