Abstract

The electronic structure of hexagonal boron nitride ({\it h}-BN) is explored using measurements of x-ray absorption and resonant inelastic x-ray scattering (RIXS) at the nitrogen K edge (1{\it s}) in tandem with calculations of the same using many-body perturbation theory within the {\it GW} and Bethe-Salpeter equation (BSE) approximations. Our calculations include the effects of lattice disorder from phonons activated thermally and from zero point energy and highlight the influence of disorder on near-edge x-ray spectra.
