Abstract

Nitrogen-vacancy (NV) centers in diamond can be read out optically or electrically. To better understand the physics of their internal electronic transitions as well as ionization and recharging, we study the spin contrast observed in both readout methods as a function of the excitation wavelength for both single NV centers and ensembles. While the optical readout works best between 525 and 550 nm, the highest electrical spin contrast is achieved by resonantly exciting the NV0 zero-phonon line at 575 nm. Additional spectral features attributed to a further excited state of NV−, phonon sidebands and tunnel coupling to nitrogen donors are observed and discussed.

金刚石NV中心的光学和电学读数与激发波长有关

金刚石中的氮空位（NV）中心可以用光学或电学方法读出。为了更好地理解其内部电子跃迁以及电离和充电的物理性质，我们研究了两种读出方法中观察到的自旋对比作为单个NV中心和系综激发波长的函数。虽然光学读数在525和550 nm之间工作得最好，但最高的电自旋对比度是通过在575 nm处共振激发NV0零声子线来实现的。另外的光谱特征归因于进一步激发态的NV−，声子边带和隧道耦合氮供体被观察和讨论。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
