Controlled Synthesis of Organic/Inorganic van der Waals Solid for Tunable Light-Matter Interactions

Abstract

High-quality organic and inorganic van der Waals (vdW) solids are realized using methylammonium lead halide (CH3NH3PbI3) as the organic part (organic perovskite) and 2D inorganic monolayers as counterparts. By stacking on various 2D monolayers, the vdW solids exhibit dramatically different light emissions. Futhermore, organic/h-BN vdW solid arrays are patterned for red-light emission.
