Influence of Disorder and Anharmonic Fluctuations on the Dynamical Rashba Effect in Purely Inorganic Lead-Halide Perovskites
Arthur Marronnier, Guido Roma, Marcelo Carignano +5
Doping organic metal-halide perovskites with cesium could be the best solution to stabilize highly-efficient perovskite solar cells. The understanding of the respective roles of th…
Lattice phonon modes of the spin crossover crystal [Fe(phen)2(NCS)2] studied by THz, IR, Raman spectroscopies and DFT calculations
Eric Collet, Giovanni Azzolina, Tomoaki Ichii +9
[Fe(phen)2(NCS)2] is a prototype transition metal complex material, which undergoes a phase transition between low-spin (LS) and high-spin (HS) phases, induced by temperature, pres…
The structure of near stoichiometric Ge-Ga-Sb-S glasses: a reverse Monte Carlo study
Ildikó Pethes, Virginie Nazabal, Radwan Chahal +5
The structure of GeGaSbS and GeGaSbS glasses was investigated by neutron diffraction (ND), X-ray diffraction (XRD), and extende…
A universal description of III-V/Si epitaxial growth processes
I. Lucci, S. Charbonnier, L. Pedesseau +15
Here, we experimentally and theoretically clarify III-V/Si crystal growth processes. Atomically-resolved microscopy shows that mono-domain 3D islands are observed at the early stag…
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…
Chemical order in Ge-Ga-Sb-Se glasses
Ildikó Pethes, Radwan Chahal, Virginie Nazabal +4
The short range order in GeGaSbSe and GeGaSbSe glasses was investigated by X-ray (XRD) and neutron diffraction (ND) as well as…
