摘要 |
A diamond crystal according to the present invention has an NV region containing a complex (NV center) of nitrogen substituted with a carbon atom and a vacancy located adjacent to the nitrogen, on a surface or in the vicinity of the surface, wherein the NV region has a donor concentration equal to or higher than the concentration of the NV centers, or a crystal of the NV region is a {111} face or a face having an off-angle that is ±10 degrees or less against the {111} face, and a principal axis of the NV center is a <111> axis that is perpendicular to the {111} face. Such a diamond crystal enables almost 100% of the NV center to be a state (NV−) of having a negative electric charge, and spin states of the NV− centers to be aligned in one direction. |
