It is showed in this thesis that temperature is very important to single photon detection, but too low temperature is not good for detection because of afterpulse and the breakdown voltage. 本文的研究表明,温度对单光子探测有着非常重要的影响,考虑到后脉冲的影响以及雪崩电压的变化,温度并不是越低越好。
It is shown that the afterpulse probability is mainly dependent on two trap levels. 测量结果显示,后脉冲概率主要受两个俘获能级的影响;
