Abstract

我们从单个 InAs/GaAs 自我装配的 Stranski-Krastanow 量点在单个光子排放上报导直到 80 K 在下面搏动并且连续波浪刺激。在温度 80 K，在零次延期的秒顺序关联功能， g (2 )(0 ) ，被测量为搏动的刺激是 0.422。在在连续波浪刺激下面的一样的温度，光子 antibunching 效果被观察。因此，我们的试验性的结果在液体氮温度在单个光子排放演示自我装配的 InAs/GaAs 量点的一个有希望的潜在的应用程序。[从作者抽象]

刺激力量依赖者微光致发光的系列和光子关联测量被用来学习光性质和单个 InAs 量点的光子统计。激子和双性人激子排出物，分别地，紧张其光致发光让线性、二次的刺激驱动依赖，被识别。在搏动的激光刺激下面，零预定相应于激子排放的第二顺序关联功能的延期山峰很好被压制，它是单个光子排放的一条清楚的证据。

We report on the single photon emission from single InAs/GaAs self-assembled Stranski–Krastanow quantum dots up to 80 K under pulsed and continuous wave excitations. At temperature 80 K, the second-order correlation function at zero time delay, g (2) (0), is measured to be 0.422 for pulsed excitation. At the same temperature under continuous wave excitation, the photon antibunching effect is observed. Thus, our experimental results demonstrate a promising potential application of self-assembled InAs/GaAs quantum dots in single photon emission at liquid nitrogen temperature.
