Coulomb engineering of the bandgap and excitons in two-dimensional materials

Coulomb engineering of the bandgap and excitons in two-dimensional materials

Electronic bandgap tuning in semiconductors enables key functionalities in solid-state devices. Here, the authors present a strategy to control the bandgap of atomically thin WS2 and WSe2semiconductors via manipulation of the surrounding dielectric environment rather than by modifications of the mat...
