金刚石中氮空位发光中心电荷态的局域化学开关

Localized chemical switching of the charge state of nitrogen-vacancy luminescence centers in diamond

摘要:

我们提出了一种用于控制半导体近表面发光中心电荷态的束引导化学技术。具体而言,我们氟化的H-终止的金刚石表面的电子束照射在NF 3蒸汽的存在下。氮空位处理作为一种局部化学开关,将氮空位发光中心的电荷状态从中性改变为负态。电子束衍射过程是高度局部化的,并且可以用于控制由电子束扫描的各个纳米金刚石和表面区域的发射光谱

英文摘要:

We present a beam-directed chemical technique for controlling the charge states of near-surface luminescence centers in semiconductors. Specifically, we fluorinate the surface of H-terminated diamond by electron beam irradiation in the presence of NF3 vapor. The fluorination treatment acts as a local chemical switch that alters the charge state of nitrogen-vacancy luminescence centers from the neutral to the negative state. The electron beam fluorination process is highly localized and can be used to control the emission spectrum of individual nanodiamonds and surface regions scanned by the electron beam
