我们展示了嵌入在纳米线中的位置控制的III-氮化物量子点在室温下触发的单光子发射。此外，我们还发现了单光子统计的显著的温度不敏感性，并且在300K时的g((2))[0]值仅为0.13。结合使用高质量、小的、位置控制的量子点和宽带隙材料系统，对于提供足够的激子限制和最小污染的发射光谱，从而实现室温操作至关重要。这种单光子发射器阵列将用于室温量子信息处理应用，如片上量子通信。
We demonstrate triggered single photon emission at room temperature from a site-controlled III-nitride quantum dot embedded in a nanowire. Moreover, we reveal a remarkable temperature insensitivity of the single photon statistics, and a g((2))[0] value at 300 K of just 0.13. The combination of using high-quality, small, site-controlled quantum dots with a wide-bandgap material system is crucial for providing both sufficient exciton confinement and an emission spectrum with minimal contamination in order to enable room temperature operation. Arrays of such single photon emitters will be useful for room-temperature quantum information processing applications such as on-chip quantum communication.
