Decoupled molecular and inorganic framework dynamics in CH $_{3}$ NH $_{3}$ PbCl $_{3}$

M. Songvilay, Zitian Wang, V. Garcia Sakai +7

The organic-inorganic lead halide perovskites are composed of organic molecules imbedded in an inorganic framework. The compounds with general formula CH $_{3}$ NH $_{3}$ PbX $_{3}$ (MA…

Common acoustic phonon lifetimes in inorganic and hybrid lead halide perovskites

M. Songvilay, N. Giles-Donovan, M. Bari +12

The acoustic phonons in the organic-inorganic lead halide perovskites have been reported to have anomalously short lifetimes over a large part of the Brillouin zone. The resulting…

Electric field effect on short-range polar orders in a relaxor ferroelectric system

Zhijun Xu, Fei Li, Shujun Zhang +4

Short-range polar orders in the relaxor ferroelectric material PbMg $_{1/3}$ Nb $_{2/3}$ O $_{3}$ - $28%$ PbTiO $_{3}$ (PMN-28PT) have been studied using neutron diffuse scattering. An externa…
