首次报道了生长在Si（001）衬底上的单个CdTe量子点（QD）的触发单光子发射。量子点的发射波长可以使用聚焦的激光束在宽光谱范围内（超过8 meV）进行调谐。一个近乎完美的单光子发射的激子线被保存，即使在能量调谐。还测量了激光处理前后的寿命，没有观察到明显的变化。
Triggered single-photon emission from a single CdTe quantum dot (QD) grown on Si(001) substrate is demonstrated for the first time. The emission wavelength of QDs can be tuned in a wide spectral range (more than 8 meV) using a focused laser beam. A nearly perfect single-photon emission from the exciton lines is preserved even after energy tuning. The lifetime is also measured before and after laser processing, and no appreciable change is observed.
