Non-polar nitride single-photon sources are developed in order to minimise the undesired side effects caused by the internal fields of polar nitrides, while retaining the benefits of high-temperature single-photon generation from a semiconductor quantum dot platform. As a relatively newer single-photon source, several reports have already been made highlighting their interesting optical and photophysical properties. These include an average ultrafast radiative exciton recombination lifetime of <200 ps, an average slow-timescale spectral diffusion of <40 μ eV, polarisation-controlled single-photon generation up to 220 K, and temperature-dependent fine-structure splitting. In this review, the photophysics, improvement of optical properties, and future of non-polar nitride single-photon sources will be closely examined based on current reports in the literature.

非极性氮化物单光子源

开发非极性氮化物单光子源是为了最大程度地减少由极性氮化物内部场引起的不良副作用，同时保留从半导体量子点平台生成高温单光子的好处。作为一种相对较新的单光子源，已经有一些报道强调了它们有趣的光学和光物理性质。这些包括平均超快辐射激子复合寿命<200 ps，平均慢时光谱扩展<40μeV，偏振控制的单光子产生高达220 K，以及与温度有关的精细结构分裂。在这篇评论中，光物理，光学特性的改善，
