论文摘要
固态单光子发射器（SPE），例如六角形氮化硼（HBN）内的明亮，稳定，室温缺陷（HBN）对量子信息科学应用的兴趣越来越大。迄今为止，HBN中SPE的原子和电子起源尚不清楚，并且没有研究报告了光更具光更具光色素或探索HBN SPE之间的互相关。在这里，我们将量子效率和微量发光（$μ$ PL）光谱的辐射时间依赖性度量与两色汉伯里汉伯里棕色 - 扭转干涉率结合在一起，以实现对HBN虚假的电子结构的研究。我们在HBN SPE中鉴定了光色素，该光更色变色表现出互相关以及两种零音波线的发射之间的相关量子效率。
Solid-state single-photon emitters (SPEs) such as the bright, stable, room-temperature defects within hexagonal boron nitride (hBN) are of increasing interest for quantum information science applications. To date, the atomic and electronic origins of SPEs within hBN are not well understood, and no studies have reported photochromism or explored cross-correlations between hBN SPEs. Here, we combine irradiation-time dependent measures of quantum efficiency and microphotoluminescence ($μ$PL) spectroscopy with two-color Hanbury Brown-Twiss interferometry to enable an investigation of the electronic structure of hBN defects. We identify photochromism in a hBN SPE that exhibits cross-correlations and correlated quantum efficiencies between the emission of its two zero-phonon lines.
