论文摘要
不均匀的拓宽是将HBN中量子发射器应用于综合量子光子学的主要限制。在这里，我们证明了发射波长为436 nm的蓝色发射器对电场的敏感性不如HBN中的其他量子发射极物种敏感。我们对Stark偏移的测量表明，对于这些中心具有显着的二次鲜明效应的这些中心的过渡偶极矩。使用这些结果，我们采用了DFT计算来确定具有较小的过渡偶极矩的可能点缺陷，这可能是HBN中蓝色发射器的来源。
Inhomogeneous broadening is a major limitation for the application of quantum emitters in hBN to integrated quantum photonics. Here we demonstrate that blue emitters with an emission wavelength of 436 nm are less sensitive to electric fields than other quantum emitter species in hBN. Our measurements of Stark shifts indicate negligible transition dipole moments for these centers with dominant quadratic stark effect. Using these results, we employed DFT calculations to identify possible point defects with small transition dipole moments, which may be the source of blue emitters in hBN.
