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…
In-situ Silicon Doped hBN by High-Temperature Molecular Beam Epitaxy Enables Single Photon Emission
Jiyun Kim, Nika Teran, Juliette Plo +8
Hexagonal boron nitride (hBN) has emerged as a leading host for optically active quantum defects. Yet introduction of specific impurity species other than carbon remains unexplored…
Optical detection of the electron spin resonances of G centers in silicon
Félix Cache, Krithika V. R., Tobias Herzig +8
Color centers in silicon are emerging as promising platforms for quantum technologies. Among them, the G center has attracted considerable interest owing to its bright telecom O-ba…
Spin defects in hexagonal boron nitride as two-dimensional strain sensors
Z. Mu, Z. Zhang, J. Fraunié +5
Lattice deformation is a powerful way to engineer the properties of two-dimensional (2D) materials, making their precise measurement an important challenge for both fundamental sci…
A single optically detectable tumbling spin in silicon
Félix Cache, Yoann Baron, Baptiste Lefaucher +9
We demonstrate single spin spectroscopy of a fluorescent tumbling defect in silicon called the G center, behaving as a pseudo-molecule randomly reorienting itself in the crystallin…
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…
