Pseudospin-phonon pretransitional dynamics in lead halide hybrid perovskites
B. Hehlen, P. Bourges, B. Rufflé +9
The low frequency lattice vibrations and relaxations are investigated in single crystals of the four 3D hybrid organolead perovskites, MAPbBr, FAPbBr, MAPbI, and -FA…
Landau Theory for Non-Symmetry-Breaking Electronic Instability Coupled to Symmetry-Breaking Applied to Prussian Blue Analogue
Giovanni Azzolina, Roman Bertoni, Claude Ecolivet +3
Different types of ordering phenomena may occur during phase transitions, described within the universal framework of the Landau theory through the evolution of one, or several, sy…
Elastic softness of hybrid lead halide perovskites
A. C. Ferreira, A. Létoublon, S. Paofai +10
Much recent attention has been devoted towards unravelling the microscopic optoelectronic properties of hybrid organic-inorganic perovskites (HOP). Here we investigate by coherent…
Incoherent Quasielastic Neutron Scattering Study of Molecular dynamics of 4-n-cyano-4'-octylbiphenyl
Ronan Lefort, Denis Morineau, Régis Guégan +4
We report incoherent quasielastic neutron scattering experiments on the thermotropic liquid crystal 4-n-cyano-4'-octylbiphenyl. The combination of time-of-flight and backscattering…
Sliding and translational diffusion of molecular phases confined into nanotubes
Rémi Busselez, Claude Ecolivet, Régis Guégan +5
The remaining dynamical degrees of freedom of molecular fluids confined into capillaries of nano to sub-nanometer diameter are of fundamental relevance for future developments in t…
Structure and relaxation processes of an anisotropic molecular fluid confined into 1D nanochannels
Ronan Lefort, Denis Morineau, Régis Guégan +3
Structural order parameters of a smectic liquid crystal confined into the columnar form of porous silicon are studied using neutron scattering and optical spectroscopic techniques.…
