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...

Single‐Photon Emitters Based on Ge‐V Centers in Nanoparticles Obtained From CVD‐Grown Nanocrystalline Diamond Films

A method for obtaining luminescent diamond nanoparticles doped with germanium from nanocrystalline diamond (NCD) films grown by microwave plasma‐assisted chemical vapor deposition (MPCVD) is presented. Thermal etching in the presence of an alkali metal nitrate enables the selecti...
