Researchers uncover unusual effects on the electronic structure of TMDs

To understand how a TMD semiconductor behaves inside a device, researchers investigated the effects of sub-monolayer deposition of alkali atoms at the surface of the semiconductor tungsten selenide. These deposited atoms mimics the electric field effects that a semiconductor would experience inside a transistor, while allowing researchers to directly analyse the electronic structure by a state of the art spectroscopic technique.
