The perturbed free induction decay (PFID) observed in ultrafast infrared spectroscopy was used to unveil the rates at which different vibrational modes of the same atomic-scale defect can interact with their environment. The N_{3}VH^{0} defect in dia

Conventional single-phase cooling systems are no longer able to meet the cooling demands of modern electronics. Decreasing size and increasing processing power result in increasing heat flux densities [1]. Multiphase systems are therefore proposed du

The defect in diamond formed by a vacancy surrounded by three nearest-neighbor nitrogen atoms and one carbon atom, [Formula: see text], is found in the vast majority of natural diamonds. Despite [Formula: see text] being the earliest electron paramag

Irradiating diamond with electrons or neutrons produces the electron paramagnetic resonance (EPR) R1 centre which has been shown to be a di-〈001〉-split interstitial. We report that on cooling below a certain threshold temperature and illuminating

A previously unreported defect, which is labeled $O3,$ has been observed in the EPR spectrum of synthetic type-IIa diamonds irradiated at 100 K with 2 MeV electrons. This defect was not observed in identical diamonds whose temperature during electron

Electron paramagnetic resonance (EPR) and optical absorption data on the negative and neutral vacancy in diamond are presented. We determine directly the constant of proportionality between the concentration of V- and the integrated intensity of its

We present a study of the point defects observed in as-grown and annealed synthetic diamonds using electron paramagnetic resonance (EPR) and infrared spectroscopy. The diamonds were grown by the temperature gradient HPHT method in a split sphere appa

A systematic study has been made of some of the properties of R2, the most dominant paramagnetic defect produced in type-IIa diamond by electron irradiation. R2 has been produced in high-purity synthetic diamonds, which have been irradiated with 2 Me

Diamonds grown using a cobalt/iron catalyst and annealed at 1800 degrees C were studied using two experimental techniques. A zero-phonon line, observed in photoluminescence at 2.367 eV, showed the splitting under uniaxial stress characteristic of an
