Organic-inorganic lead halide perovskite CH3NH3PbBr3 nanolaser array based on silicon grating

摘要

We report perovskite CH₃NH₃PbBr₃ nanolaser array with high density and uniform lasing wavelength on silicon. By transferring a perovskite microwire onto silicon grating, spatially periodic laser array is achieved without modifying the cavity and gain.
