Perovskite light-emitting devices with a metal–insulator–semiconductor structure and carrier tunnelling

Abstract

Organic–inorganic hybrid perovskites have been widely recognized as highly luminescent materials for efficient light-emitting devices. Herein, we report a simple perovskite-based metal–insulator–semiconductor (MIS) device structure with green light emission. Electron tunnelling and subsequent recombination in the semiconductor–insulator interface region is confirmed as the working mechanism of the perovskite light-emitting devices.
