通过微光致发光光谱研究了氮δ掺杂磷化镓中单个等电子陷阱的发光。人们发现这些单个陷阱发射的光子在发射能量和亮度方面几乎相同。此外，在 30 K 的连续光激发下，单氮对的单光子发射被证实为强反聚束。这些结果意味着 GaP 中的单氮对可能有助于实现能量定义的单光子的独特来源，甚至是不可区分的光子。
Luminescence from single isoelectronic traps in nitrogen δ-doped gallium phosphide was studied by micro-photoluminescence spectroscopy. These single traps were found to emit photons that were nearly identical in both emission energy and brightness. Furthermore, single photon emission from a single nitrogen pair is confirmed by a strong antibunching under continuous optical excitation at 30 K. These results imply that single nitrogen pairs in GaP might be useful for realizing unique sources of energetically-defined single photons, and even indistinguishable photons.
