Laser Terahertz Emission Microscope for Imaging Grain Heterogeneity: A Case Study of CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> Perovskite Semiconductors

Laser Terahertz Emission Microscope for Imaging Grain Heterogeneity: A Case Study of CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> Perovskite Semiconductors

Strong terahertz (THz) emission from the methylammonium lead iodide (MAPbI<sub>3</sub>) perovskite semiconductors has been observed following above-bandgap photoexcitation, yet local THz responses of crystalline microstructures are absent. We implement laser THz emission microscope (LTEM...
