Rashba and Dresselhaus effects in doped methylammonium lead halide perovskite MAPbI.

Inorganic-organic lead halide perovskites, particularly methylammonium lead halide (MAPbI) perovskite, have been regarded as promising materials for optoelectronics and spintronics. However, the practical applications of these perovskites are limited by lead toxicity and instability under air and pressure. This study investigates the substitution of Pb with Sn and Ge in cubic MAPbI perovskite.
