Surface plasmon coupling regulated CsPbBr₃ perovskite lasers in a metal-insulator-semiconductor structure.

ABSTRACT: A strong coupling effect often occurs between a metal and semiconductor, so micro/nano-lasers based on surface plasmons can break through the optical diffraction limit and realize unprecedented linear and nonlinear enhancement of optical processes. Hence, metal-insulator-semiconductor (M-I-S) structures based on perovskite materials were explored to design optoelectronic devices. Herein, we constructed an Ag/SiO₂/CsPbBr₃ hybrid structure to generate surface plasmon coupled emission between the metal and CsPbBr₃ perovskite. Combined with experimental characterization and COMSOL Multiphysics software simulations, the best enhancement for CsPbBr₃ radiative recombination efficiencies can be achieved with a 10 nm-thickness of the SiO₂ layer
