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…

Growth of hexagonal BN crystals by traveling-solvent floating zone
Eli Zoghlin, Juliette Plo, Gaihua Ye +11
Large, high-purity single-crystals of hexagonal BN (h-BN) are essential for exploiting its many desirable and interesting properties. Here, we demonstrate via X-ray tomography, X-r…
