Spontaneous emission of light by non-equilibrium phonons
J. Plo, P. Valvin, M. Moret +8
When a system is brought out of equilibrium by an external excitation, its relaxation to thermodynamic equilibrium generates phonons. These non-equilibrium phonons degrade via casc…

Growth of rhombohedral boron nitride crystals using an iron flux
W. Desrat, M. Moret, J. Plo +7
We report the growth of high quality rhombohedral boron nitride (rBN) crystals by the iron flux method at atmospheric pressure. In contrast to the lamellar structure of standard he…

InSe as a case between 3D and 2D layered crystals for excitons
W. Desrat, T. V. Shubina, M. Moret +3
We demonstrate the successive appearance of the exciton, biexciton, and P band of the exciton-exciton scattering with increasing excitation power in the photoluminescence of indium…
