我们利用微波辅助等离子体化学气相沉积的方法合成了单晶金刚石，并对金刚石辐射探测器的温度特性进行了评价。在473K下，空穴的电荷收集效率为96.9%，能量分辨率为3.0%。对于电子，在高于373K的温度下，它们是不可检测的。可能是频率引起的载流子陷阱或漏电流增加。由钻石中金刚石探测器有限公司生产的探测器在523K下正常工作，电子可以在573K下测量到。我们讨论了金刚石探测器中电荷载流子输运的特性，为将来在更高温度下使用做准备。
We synthesized single-crystal diamonds using microwave assisted plasma chemical vapor deposition and evaluated the temperature dependence of the diamond radiation detectors. We achieved charge collection efficiency of the hole of 96.9% with 3.0% energy resolution at 473 K. In the case of electrons, they became undetectable at temperatures higher than 373 K. It is possible that carrier trapping generated with frequency or the leakage current increased. The detector produced by the diamond in Diamond Detector Ltd. detector, operates normally at 523 K. Electrons can be measured at 573 K. We discussed the characteristics of charge carrier transport in the diamond detector to prepare for future use at higher temperatures.
