摘要：
Method is presented to obtain current-mode responsivity from diamond photodiode in the soft X-ray range (0.25-7 keV). Pulsed bias and blocking contacts are used to mitigate artifacts of charge trapping and photoconductive gain. Mean electron-hole pair creation energy is measured from experimental data to be 13.25 +/- 0.5eV. Responsivity of diodes made from commercially available 500 mu m thick single-crystal diamond (under conditions described) is reported. Published by Elsevier B.V.
