Hanan Dery (University of Rochester) Abstract: Hydrogen-like bound states of photoexcited electron-hole pairs in semiconductors -- that is, excitons -- have been a focus of considerable study for more than half a century. In undoped direct-gap semiconductors, neutral excitons comprise the photogenerated electron and hole in the conduction and valence bands (CB and VB), respectively,… Read More »Hexcitons and oxcitons in monolayer WSe2. – (Hanan Dery / LPCNO / Seminar). – 12/07/2022
