Broadband critical dynamics in disordered lead-based perovskites
C. Stock, M. Songvilay, P. M. Gehring +2
Materials based on the cubic perovskite unit cell continue to provide the basis for technologically important materials with two notable recent examples being lead-based relaxor pi…
Decoupled molecular and inorganic framework dynamics in CHNHPbCl
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 CHNHPbX (MA…
Lifetime-shortened acoustic phonons and static order at the Brillouin zone boundary in the organic-inorganic perovskite CHNHPbCl
M. Songvilay, M. Bari, Z. -G. Ye +7
Lead halide hybrid perovskites consist of an inorganic framework hosting a molecular cation located in the interstitial space. These compounds have been extensively studied as they…
Depth dependant element analysis of PbMgNbO using muonic X-rays
K. L. Brown, C. P. J. Stockdale, H. Luo +8
The relaxor PbMgNbO (PMN) has received attention due to its potential applications as a piezoelectric when doped with PbTiO (PT). Previous results have…
From soft harmonic phonons to fast relaxational dynamics in CHNHPbBr
I. P. Swainson, C. Stock, S. F. Parker +3
The lead-halide perovskites, including CHNHPbBr, are components in cost effective, highly efficient photovoltaics, where the interactions of the molecular cations…
Evidence for anisotropic polar nanoregions in relaxor PMN: A neutron study of the elastic constants and anomalous TA phonon damping
C. Stock, P. M. Gehring, H. Hiraka +6
We use neutron scattering to characterize the acoustic phonons in the relaxor PMN and demonstrate the presence of an anisotropic damping mechanism directly related to short-range,…
