Description:
Coulomb engineering of the bandgap and excitons in two-dimensional materials Nature Communications, Published online: 4 May 2017; doi:10.1038/ncomms15251 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 WS 2 and WSe 2 semiconductors via manipulation of the surrounding dielectric environment rather than by modifications of the materials themselves.
