Electron paramagnetic resonance detection of the giant concentration of nitrogen vacancy defects in sintered detonation nanodiamonds
A giant concentration of nitrogen vacancy defects has been revealed by the electron paramagnetic resonance (EPR) method in a detonation nanodiamond sintered at high pressure and temperature. A high coherence o...

EPR identification of the triplet ground state and photoinduced population inversion for a Si-C divacancy in silicon carbide
It is shown that intrinsic defects responsible for the semi-insulating properties of SiC represent Si-C divacancies in a neutral state (V Si-V C)0, which have the triplet ground state. The energy level scheme and...
