“…Diamond is an attractive material for use in radiation detectors, primarily due to the high lifetime and mobility values for both charge carrier types, high resistivity (up to 10 14 Ω cm), high radiation tolerance and high temperature operation, low relative dielectric permittivity (5.7), and the highest breakdown field (10 MV cm −1 ) in comparison with other semiconductors . These properties’ combination makes detectors based on diamond perfectly suitable for extreme operating conditions.…”

Various samples of multisectoral high‐pressure high‐temperature (HPHT) single‐crystal diamond plate (IIa type) (4 × 4 × 0.53 mm) are tested for particle detection applications. The samples are investigated by X‐ray diffractometry, photoluminescence spectroscopy, Raman spectroscopy, Fourier‐transform infrared, and visible/ultraviolet (UV) absorption spectroscopy. High crystalline perfection and low impurity concentration (in the {100} growth sector) are observed. To investigate detector parameters, circular 1.0 and 1.5 mm diameter Pt Schottky barrier contacts are created on {111} and {100} growth sectors. On the backside, a Pt contact (3.5 × 3.5 mm) is produced. The {100} growth sector is proved to be a high‐quality detector: the full width at half maximum energy resolution is 0.94% for the 5.489 MeV 226Ra α‐line at an operational bias of +500 V. Therefore, it is concluded that the HPHT material {100} growth sector is used for radiation detector production, whose quality is not worse than the chemical vapor deposition method or specially selected natural diamond detectors.

Electrolysis of D2O may be used as a portable neutron source with numerous applications without the complexity of huge reactor operations. Herein, we report reproducible fast neutron generation by electrolysis of D2O using palladium cathode and platinum anode, which was detected with diamond detector, gas filled 3He detectors after thermalisation with high density polythene, as well as novel epoxy resin and CR-39 detectors. Notably, a highly reproducible neutron generation at electrochemical surfaces of palladium electrode was observed and signature transmutation via Pd (d, n) Ag was corroborated. This was further explained using a theoretical model based on second order quantum perturbation theory.

“…Due to their high atomic density, strong bonding, and crystal structure of high symmetry, diamonds show high Raman gain coefficient, which makes them suitable for high power diamond Raman lasers [6]. With a wide bandgap of 5.5 eV, a high breakdown field, high carrier mobility, and high radiation hardness, diamonds are an ideal material for high energy particle and ionizing radiation detection [7][8][9][10]. Furthermore, diamonds exhibit exceptional electronic properties, such as a high breakdown field (>10 MV/cm) and high carrier mobility (4500 cm 2 /Vs for electrons and 3800 cm 2 /V for holes), which makes diamond an excellent candidate for next generation semiconductor materials [11,12].…”

Single crystal diamonds were deposited on high pressure high temperature (HPHT) substrate with high growth rate, up to 18.5 μm/h, by using dual radio-frequency inductive coupled plasma jet. The methane flux was found to influence the growth rate of single crystal diamond. The reason for this might be ascribed to the electron temperature increase, raising the flux of methane, based on the plasma diagnosis results by optical emission spectra (OES). The results of Raman spectroscopy and the X-ray rocking-curve indicated that as-deposited diamonds are of good quality.
