Control of CH₃NH₃PbI₃ Perovskite Nanostructure Formation through the Use of Silicon Nanotube Templates

A new route to formation of methylammonium lead iodide perovskite nanostructures is reported whose dimensions are controlled by the use of porous silicon nanotube templates. Optical absorption and photoluminescence properties for perovskite nanostructures of 70 and 200 nm in width are evaluated, along with comparisons with larger 1D microwires of the same composition.
