摘要：

Free-standing polycrystalline diamond films grown by microwave plasma CVD technique were tested for detection X-ray radiation from a synchrotron source. Two different configurations of collection electrodes on diamond were used. The first (sandwich) geometry uses a thin amorphous conducting layers formed by nitrogen ion irradiation on both sides of the diamond plate. The second (planar) one, which showed better characteristics, comprises of an interdigitated planar array of metallic contacts on a face exposed to photon flux. However, in both cases a polarization effect that leads to a decrease of the detector response with exposition time, was observed. Better device performance is expected for diamond films of improved quality.
