Associate Professor Adda Athanasopoulos-Zekkos deployed in New Zealand following the November 13, 2016, magnitude 7.8 earthquake to map landslides, liquefaction, fault rupture and other natural hazards associated with this major earthquake event. It is estimated that nearly 100,000 landslides occurred during this major earthquake. Athanasopoulos-Zekkos has been in New Zealand for nearly two weeks as part of the GEER (Geotechnical Engineering Extreme Events) U.S. team of engineers and scientists to collect perishable data on this major event.

Her work was featured in a December 6, 2016, article in the Marlborough Express.

The University of Michigan’s research team, including Adda Athanasopoulos-Zekkos and Dimitrios Zekkos, is featured in a December 13, 2016, Michigan News article.

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
