The nature of dynamic local order in CHNHPbI and CHNHPbBr
Nicholas Weadock, Tyler Sterling, Julian Vigil +12
Hybrid lead halide perovskites (LHPs) are a class of semiconductor with novel properties that are distinctively governed by structural fluctuations. Diffraction experiments sensiti…
Fast broadband cluster spin-glass dynamics in PbFeNbO
C. Stock, B. Roessli, P. M. Gehring +11
PbFeNbO (PFN) is a relaxor ferroelectric (T 400 K) consisting of disordered magnetic Fe (S=, L0) ions resulting in a l…
On the question of dynamic domains and critical scattering in cubic methylammonium lead triiodide
Nicholas J. Weadock, Peter M. Gehring, Aryeh Gold-Parker +3
We investigate the hypothesis of dynamic tetragonal domains occuring in cubic CHNHPbI using high-resolution neutron spectroscopy to study a fully deuterated single crys…
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…
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…
