Fabrication of Lead Halide Perovskite Thin Films by Laser Alternate Deposition: Variation of Physical Properties with Layered Structure

We aim to reveal the correlation between the structure and physical properties of lead halide perovskite thin films fabricated by laser deposition method while artificially controlling the crystal structure. We found that the crystal phase of methylammonium lead iodide perovskite (CH3NH3PbI3, MAPbI3) thin films formed by alternating laser deposition of lead iodide (PbI2) and methylammonium iodide (CH3NH3I, MAI) at room temperature depends on the layered structure.
