Local structure in PMN-PT relaxor ferroelectrics
The proposed experiments will provide neutron total-scattering data for elucidating the nanoscale ordering of polar atomic displacements that underlie the commercially viable... -
Variable Temperature Study of thallium and caesium azides
This proposal seeks to investigate the effect of temperature on the structures of thallium and caesium azide. High-resolution neutron powder diffraction data are necessary to... -
Atomic structure of formamidinium lead iodide perovskite
New perovskite phases containing lead and halogens with a molecular cation are providing new options for materials in solar cells, giving unusually high efficiencies in...
