Upconverted electroluminescence via Auger scattering of interlayer excitons in van der Waals heterostructures
Abstract
The authors present electroluminescence measurements of light-emitting devices based on van der Waals heterostructures, and observe a lower than expected threshold voltage for intralayer electroluminescence, attributed to non-radiative Auger-type recombination of interlayer excitons and resulting energy transfer.
