Indirect to direct bandgap transition in methylammonium lead halide perovskite

Puntos clave

Los puntos clave no están disponibles para este artículo en este momento.

Resumen

Unusually long charge carrier lifetime in methylammonium lead halide perovskites is a result of the Rashba-split indirect bandgap. At high pressure the bandgap becomes purely direct, with shorter carrier lifetime and higher radiative efficiency.
