Abstract

We present an experimental study of the longitudinal and transverse relaxation of ensembles of negatively charged nitrogen-vacancy (NV-) centers in a diamond monocrystal prepared by 1.8 MeV proton implantation. The focused proton beam was used to introduce vacancies at a 20 µµm depth layer. Applied doses were in the range of 1.5×1013 to 1.5×1017 ions/cm2. The samples were subsequently annealed in vacuum which resulted in a migration of vacancies and their association with the nitrogen present in the diamond matrix. The proton implantation technique proved versatile to control production of nitrogen-vacancy color centers in thin films.

摘要

我们展示了一项关于通过1.8兆电子伏特质子注入制备的金刚石单晶中带负电的氮空位（NV-）中心系综的纵向和横向弛豫的实验研究。聚焦质子束用于在20微米深度层引入空位。施加剂量范围为1.5×10¹³至1.5×10¹⁷离子/平方厘米。随后将样品在真空中退火，这导致空位迁移并与金刚石基质中存在的氮结合。质子注入技术被证明在控制薄膜中氮空位色心的产生方面具有通用性。
