Abstract
Section titled āAbstractāOxygen-containing plasma termination of the surface of diamond detectors of the time of flight of high-energy protons for leakage-current reduction is investigated. To this end, platinum electrical contacts with a complex shape are made on the surface of diamond using sputtering and explosive photolithography, and their current-voltage characteristics are analyzed. Dark leakage currents via, presumably, the surface states of diamond, which form because of violation of surface termination, are studied. Methods for reducing leakage currents by 2 to 3 orders of magnitude using surface treatment in oxygen-containing plasma (without high-temperature annealing) are developed. After treatment, the leakage currents of all fabricated detectors do not exceed 200 pA at a voltage up to Ā±850 V, which corresponds to the requirements imposed on detectors of this type.
