Radiative recombination of near-surface donor–acceptor pairs in hydrogenated homoepitaxial diamond nanolayers

Hydrogen-terminated diamond is known for its p-type surface conductivity, which arises from a near-surface hole accumulation layer induced by adsorbed acceptor species. Here, we demonstrate that these surface acceptors also form optically active donor–acceptor pairs (DAPs) with s...
