Dimitrios Zekkos’ Team Use Drones to Aid Archaeology

Dimitrios Zekkos and some of his students spent part of the 2016 summer in northeastern Greece. | Short Read

They were working at an archaeological-dig site, a spot where the city Olynthos existed before Macedonians attacked in 348 bc.

Zekkos’ team flew drones to create a map of the archaeological excavation and the archaeological site.

An article about the site appears in the Fall 2016 issue of LSA Magazine.

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
