About this video

A groundbreaking new semiconductor compound may lead to smaller, faster, less power-hungry electronics. It’s the first to build spintronic properties into a material that’s stable at room temperature and easily tailored to a variety of applications.

The new compound could eventually be used as the base material for spintronic processors and other devices, much like silicon is the base for electronic computing devices.

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
