Abstract
Lead-chalcogenides and lead-halide-perovskites exhibit similar physical properties, which can be summarized as defect tolerant behavior. While the lead-chalcogenides have been pioneering materials in vapor phase epitaxy, metal-halide-perovskites offer the possibility for epitaxial growth from solutions by techniques such as spin or drop casting. The obtained microstructures show promising optical properties, and in a showcase example of formamidinium-lead-tribromide on lead sulfide, we show first lasing results. These results open up several perspectives for solution epitaxial structures, including electrically pumped quantum devices, demanded not only for lighting but also for quantum information technology, which would be another milestone achievement for metal–halide semiconductors.
