Organic-inorganic halide perovskites have achieved remarkable success in various optoelectronic devices. A high-quality CH<sub>3</sub>NH<sub>3</sub>PbBr<sub>3</sub> single-crystalline thin film has been directly grown in a micrometer gap between a pair of distributed reflectors with over 99.9% reflectivity, which naturally form a vertical cavity surface-emitting laser device with a single mode or several modes. The single-crystalline perovskite has an exciton lifetime of 426 ns and evidence of t ...[more]
