摘要
Hybrid organic–inorganic perovskites(HOIPs)are introducing exotic directions in the photovoltaic materials landscape.The coexistence of inversion symmetry breaking and spin–orbit interactions play a key role in their optoelectronic properties.We perform a detailed study on a recently synthesized ferroelectric layered HOIP,(AMP)PbI_(4)(AMP=4-aminomethyl-piperidinium).The calculated polarization and Rashba parameters are in excellent agreement with experimental values.
