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…
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.…
Donor-acceptor recombination emission in hydrogen-terminated nanodiamond: Novel single-photon source for room-temperature quantum photonics
D. G. Pasternak, A. M. Romshin, R. H. Bagramov +9
In fluorescence spectra of nanodiamonds (NDs) synthesized at high pressure from adamantane and other organic compounds, very narrow (~1 nm) lines of unknown origin are observed in…
Raman fingerprints of ultrasmall nanodiamonds produced from adamantane
O. S. Kudryavtsev, R. H. Bagramov, A. M. Satanin +4
The synthesis of ultrasmall (2-5 nm) nanodiamonds purely from adamantane at pressure of 12 GPa is reported. Their structural features have been studied by Raman spectroscopy. The u…
Fano-type effect in hydrogen-terminated pure nanodiamond
O. S. Kudryavtsev, R. H. Bagramov, A. M. Satanin +7
Two novel properties, unique for semiconductors: a negative electron affinity [1-2], and a high p-type surface electrical conductivity [3-4], were discovered in diamond at the end…
A new tool for precise mapping of local temperature fields in submicrometer aqueous volumes
Alexey M. Romshin, Vadim E. Zeeb, Artem K. Martyanov +6
Nanodiamond hosting temperature-sensing centers constitutes a closed thermodynamic system, with the only window of energy exchange with the environment without direct contacts of a…
Anomalous enhancement of nanodiamond luminescence upon heating
A. A. Khomich, O. S. Kudryavtsev, T. A. Dolenko +4
Characteristic photoluminescence (PL) of nanodiamonds (ND) of very different origin (detonation, HPHT, extracted from meteorite) was studied in situ at high temperatures in the ran…
