An enabling thin-film deposition technique for hybrid optoelectronic devices Adrienne Stiff-Roberts Duke University, USA Hybrid perovskites with the ability to control spin, charge, and light could establish a new semiconductor technology that is especially useful for optoelectronic devices. While CH 3 NH 3 PbI 3 (methylammonium lead triiodide, or MAPbI) easily can be solution-processed, the same is not true for hybrid perovskites comprising larger, more complex organic molecules that have incompatible solubility with metal halides. Alternatively, vapor-phase deposition of organic precursors can introduce degradation and make stoichiometric deposition with inorganic precursors more difficult. However, resonant infrared, matrix-assisted pulsed laser evaporation (RIR-MAPLE), a versatile thin-film deposition technique that features aspects of both solution-based and vapor-phase deposition, enables a wide variety of hybrid perovskite thin films that can be difficult to achieve otherwise. This talk will review the development of RIR-MAPLE growth of hybrid perovskite thin films, demonstrating application to 3D MAPbI and 2D hybrid perovskites (such as oligothiophene- and phenethylammonium-based metal halide perovskites).
