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

HIGHLIGHTS

• who: Jasmine P. H. Rivett from the Cavendish LaboratoryUniversity of Philadelphia, PA, USA have published the research: Long-lived polarization memory in the electronic states of lead-halide perovskites from local structural dynamics, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS of 17/Nov/2017
• what: The authors show that lead halide perovskites lie between these two extremes. The authors show that the polarization anisotropy can be written as A= 3 C20 B20 2 C00 B00 where Clm and Blm are the coefficients of the expansions of IIi and ni in spherical harmonics. The authors report . . .
