Barnes, and Aron Walsh The hybrid halide perovskite CH 3 NH 3 PbI 3 exhibits a complex structural behavior, with successive transitions between orthorhombic, tetragonal, and cubic polymorphs around 165 and 327 K. Herein we report first-principles lattice dynamics (phonon spectrum) for each phase of CH 3 NH 3 PbI 3 . The equilibrium … [Phys. Rev. B 92, 144308] Published Fri Oct 16, 2015
