Abstract
Section titled āAbstractāRadiation detectors in planar configuration has been fabricated using CVD grown single crystalline diamond detectors. The detectors exhibited high energy-resolution for both electrons and holes transport. The performance of the diamond detectors was found to be asymmetric with respect to the bias polarity. The optimized charge collection efficiency values and the electronic noise analysis suggested the performance of the detectors is limited by the presence of electrically active defects such as nitrogen impurity. Density functional theory-based defect calculations has been performed to determine the location within the bandgap of the plausible defects that might interfere with the charge transport.
