摘要：
A diamond-like carbon thin layer was used as an interlayer between a free-standing diamond substrate grown by microwave plasma enhanced chemical vapour deposition and a Pt/Au layer. The dark-current of about 5.0 pA cm(-2) was found for this detector at an electric field of 200 V cm(-1). Ohmic contact was achieved by this diamond-like carbon/Pt/Au trilayer structure as evidenced by a linear dark I-V curve. The ratios of photocurrent to dark-current were about 26 and 35 for diamond detectors with Ti/Pt/Au and diamond-like carbon/Pt/Au trilayer electrodes, respectively. The energy resolution for the diamond detector with diamond-like carbon/Pt/Au electrode was about 3.30%, better than 4.56% for the detector with Ti/Pt/Au electrode.
