Hybrid organic-inorganic semiconductors, such as hybrid perovskites, are crystalline materials with unique properties derived from the organic or inorganic components. Resonant infrared matrix-assisted pulsed laser evaporation (RIRMAPLE) is a gentle physical vapor deposition technique that can enable two-dimensional hybrid perovskite thin films that are difficult to realize by solution-based processing. This work describes the RIR-MAPLE deposition of a model twodimensional hybrid perovskite material system, namely phenethylammonium lead halide [(PEA)2PbX4] perovskites (n=1). Different schemes for delivery of precursor materials to the substrate, as well as different mixed halide compositions, are demonstrated using RIR-MAPLE, and the film morphology, crystal structure, and optical properties are characterized.
