Near surface donor-acceptor pairs in hydrogenated homoepitaxial diamond nanolayers
A. M. Romshin, A. P. Bolshakov, A. A. Zhivopistsev +5
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 de…

Tuning of SiV quantum emission in nitrogen-doped nanodiamonds by dual-color excitation
A. A. Zhivopistsev, A. M. Romshin, A. V. Gritsienko +8
The charge dynamics of silicon-vacancy (SiV) centers have been investigated for the first time in high-pressure high-temperature nanodiamonds (NDs) with varying concentrations of s…

Single-photon sources created by nature millions of years ago
D. G. Pasternak, A. M. Romshin, R. A. Khmelnitsky +6
Single photons source (SPS) is a key component required by quantum communication devices. We report the finding of bright diamond-based SPS created by nature millions of years ago.…
