    Fundamental understanding of the charge transport physics of hybrid lead halide perovskite semiconductors is important for advancing their use in high performance optoelectronics. We use field effect transistors (FETs) to probe the charge transport mechanism in thin films of methylammonium lead iodide (MAPbI3). We show that through optimization of thin film microstructure and source drain
