Long-lived polarization memory in the electronic states of lead-halide perovskites from local structural dynamics

Nature Communications, 2018
Anharmonic ultrafast structural dynamics are expected in lead halide perovskites due to their soft nature. Here Rivett et al. show that these dynamics lead to picosecond-long polarization anisotropy of photo-carriers in several halide perovskites, orders
