Using Pressure to Unravel the Structure-Dynamic-Disorder Relationship in Metal Halide Perovskites
Kai Xu, Luis Pérez-Fidalgo, Bethan L. Charles +3
The exceptional optoelectronic properties of metal halide perovskites (MHPs) are presumed to arise, at least in part, from the peculiar interplay between the inorganic metal-halide…
On the role of the electron-phonon interaction in the temperature dependence of the gap of lead halide perovskites
A. Francisco-López, B. Charles, O. J. Weber +5
Lead halide perovskites are causing a change of paradigm in photovoltaics. Among other peculiarities, these perovskites exhibit an atypical temperature dependence of the fundamenta…
Dynamic disorder, phonon lifetimes, and the assignment of modes to the vibrational spectra of methylammonium lead halide perovskites
Aurélien M. A. Leguy, Alejandro R. Goñi, Jarvist M. Frost +11
We present Raman and terahertz absorbance spectra of methylammonium lead halide single crystals (MAPbX3, X = I, Br, Cl) at temperatures between 80 and 370 K. These results show goo…
Lattice dynamics and vibrational spectra of the orthorhombic, tetragonal and cubic phases of methylammonium lead iodide
Federico Brivio, Jarvist M. Frost, Jonathan M. Skelton +7
The hybrid halide perovskite CH3NH3PbI3 exhibits a complex structural behaviour, with successive transitions between orthorhombic, tetragonal and cubic polymorphs at ca. 165 K and…
Melting of the Na layers in solid Na0.8CoO2
M. Weller, A. Sacchetti, H. R. Ott +2
Data of 23Na NMR spectra- and relaxation measurements are interpreted as suggesting that, upon increasing temperature the Na layers in Na0.8CoO2 adopt a 2D liquid state at T=291 K.…
Pressure induced variation of the ground state of CeAl3
M. Weller, J. L. Gavilano, A. Sacchetti +1
Pressure-induced variations of Al NMR spectra of CeAl indicate significant changes in the ground-state characteristics of this prototypical heavy-electron compound. Prev…
