Professor McCormick in earthquake engineering video

Associate Professor Jason McCormick is in a new MConnex video titled, “Make It Earthquake-Proof.” | Short Read

The video explains that modern structures are designed to absorb damages without collapsing, but an event like an earthquake can quickly escalate construction repair costs for aging buildings. CEE researchers are looking into materials rarely used in the construction world for retro-fitting older structures and providing a type of affordable earthquake insulation barrier.

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
