Paper Abstract

A diamond film was grown on alumina ceramic by micro-wave plasma chemical vapor deposition (MPCVD) and was fabricated into an interdigited alpha-particle detector. By optimizing growth parameters in MPCVD, we found that under the conditions with carbon source (alcohol/hydrogen) concentration in 0.8% and deposition temperature at 850°C, the least content of sp2 and the best quality of diamond film could be obtained. Photocurrent under α-particle irradiation was in the range of 10-5~10-4A within one hundred voltages, and dark current was about 10-9~10-8A.
