Surface recombination and out of plane diffusivity of free excitons in hexagonal boron nitride
Sébastien Roux, Christophe Arnold, Etienne Carré +11
We present a novel experimental protocol using Cathodoluminescence measurements as a function of the electron incident energy to study both exciton diffusion in a directional way a…

Radiative lifetime of free excitons in hexagonal boron nitride
Sébastien Roux, Christophe Arnold, Fulvio Paleari +12
Using a new time-resolved cathodoluminescence system dedicated to the UV spectral range, we present a first estimate of the radiative lifetime of free excitons in hBN at room tempe…
