NGA using data from Spire and Ball to monitor Arctic maritime traffic

Debra Facktor Lepore, AERO alumna and Ball’s vice president and general manager of strategic operations and commercial aerospace, said that “[t]he idea that there is a battle between public and private or between large aerospace and small aerospace is really missing the boat."
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
