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…
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…
Direct observation of electron thermalization and electron-phonon coupling in photoexcited bismuth
J. Faure, J. Mauchain, E. Papalazarou +7
We investigate the ultrafast response of the bismuth (111) surface by means of time resolved photoemission spectroscopy. The direct visualization of the electronic structure allows…
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…
