Deep Learning the Defect Landscape: Long-Timescale Vacancy Dynamics in Lead-Free Double Perovskites

Abstract 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 perovsk...

Hydrationas a Structural Switch: Controlling MagneticCoupling and CO2 Photoreduction in Transition-Metal HalidePerovskites

Abstract Transition-metal halides are of particular interest because their partially filled d-orbitals, containing unpaired electrons, give rise to distinctive magnetic and electronic properties. Notably, hydration can act as a structural switch, inducing substantial modification...
