Deep Learning the Defect Landscape: Long-Timescale Vacancy Dynamics in Lead-Free Double Perovskites
Point defects strongly influence charge transport and recombination, as well as structural stability in metal halide perovskites, yet their geometric evolution and impact on dynamic optoelectronic properties are difficult to understand. In lead-free halide double perovskites (HDPs) such as Cs2AgBiBr6, lattice anharmo...
