摘要

我们报告了一种在二氧化硅/碳化硅界面上产生单光子发射器的方法。我们通过高温氧化形成了高质量的二氧化硅/碳化硅界面，随后在较低温度（200 ℃-1000 ℃）下进行氧化以产生发光体。在 800 °C 再氧化后，我们确认形成了具有明亮发光（50 kcps）的发光体。通过 Hambury-Brown 和 Twiss 测量，证实了单光子特性。因此，所提出的方法能有效地在二氧化硅/碳化硅界面上产生高亮度的单光子发光体。

Generation of single photon emitters at a SiO2/SiC interface by high-temperature oxidation and reoxidation at lower temperatures

We report on an approach to produce single photon emitters at the SiO₂/SiC interface. We form a high-quality SiO₂/SiC interface by high-temperature oxidation and subsequently perform oxidation at lower temperatures (200 °C–1000 °C) to generate the emitters. After reoxidation at 800 °C, we confirmed the formation of emitters with a bright luminescence (>50 kcps). Through Hambury-Brown and Twiss measurements, single photon characteristics were confirmed. Thus, the proposed approach is effective in generating highly bright single photon emitters at the SiO₂/SiC interface.
