Abstract

Diamond films produced by microwave plasma enhanced chemical vapor deposition (CVD) technique and used to fabricate radiation detectors have been characterized. The polycrystalline diamond films have a measured resistivity of 10¹² Ω.cm and a carrier lifetime of about 530 ps. The carrier mobility - lifetime product depends on the density of photogenerated carriers. The carrier mobility decreases from 160 to 13 cm²/V.s for a carrier density increase from 2 × 10¹¹ cm^-3 to 3.7 × 10¹³ cm^-3. The detector response to laser pulses (λ = 355, 532 and 1064 nm), X-ray flux (2.5 - 16 keV) and alpha particles (²⁴¹Am, 5.49 MeV) has been investigated. The response speed of the detector is in the 100 ps range. X-ray photon flux measurements and alpha particle counting capabilities of the CVD diamond detectors are demonstrated.
