论文摘要
H-BN中的颜色中心是已知的最明亮的发射中心之一，但这些发射中心的起源尚不清楚。在这里，使用第一原理计算与生成函数方法结合使用，我们系统地阐明了特定缺陷与振动自由度的耦合。我们表明，许多缺陷的线形表现出很强的耦合到高频声子模式，并且c $ _ {\ text {n}} $，c $ _ {\ text {b}} $，c $ _ {\ c $ _ {\ text {b text {b}}}} $ - c $ _ c $ _ { v $ _ {\ text {b}} $可以与实验线形相关联。我们详细的理论研究是识别H-BN中光学活性缺陷的指南，该缺陷可以适合基于光子的量子技术中的特定应用，例如单光子发射器，混合自旋 - 闪光灯接口或自旋机械界面。
Color centers in h-BN are among the brightest emission centers known yet the origins of these emission centers are not well understood. Here, using first-principles calculations in combination with the generating function method, we systematically elucidate the coupling of specific defects to the vibrational degrees of freedom. We show that the lineshape of many defects exhibits strong coupling to high frequency phonon modes and that C$_{\text{N}}$, C$_{\text{B}}$, C$_{\text{B}}$-C$_{\text{N}}$ dimer and V$_{\text{B}}$ can be associated with experimental lineshapes. Our detailed theoretical study serves as a guide to identify optically active defects in h-BN that can suit specific applications in photonic-based quantum technologies, such as single photon emitters, hybrid spin-photon interfaces, or spin-mechanics interfaces.
