Origin of the Temperature-Induced Gap Bowing of Formamidinium-Methylammonium Lead Iodide Perovskites: Role of Cationic Rattlers
Kai Xu, Adrián Francisco-López, Bethan L. Charles +4
A thorough understanding of the temperature dependence of semiconductor band gaps is essential for optimizing optoelectronic devices. In this respect, the origin of the pronounced…
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…
