Thin Film Stoichiometry and Defects Management for Low Threshold and Air Stable Near‐Infrared Perovskite Laser

open access: yesAdvanced Materials, EarlyView.
As defect density in 3D perovskites is controlled by adjusting excess formamidinium iodide concentration, shallow defects acts as a carrier sink for amplified spontaneous emission (ASE). A comprehensive charge carrier dynamic model is presented to understand the critical factor of the reduction of ASE threshold.
