| 内容記述 | We established the method to fabricate two-dimensional (2D) shallow NV ensemble. We realized nitrogen-terminated (111) diamond surface with nitrogen radical exposure and grew very thin (approximately 10 nm) diamond film on the surface by microwave plasma-enhanced chemical vapor deposition (MPCVD). We counted the number of NV ensembles aligned in [111] direction of the NV ensembles which we observed. The probability of NV ensemble being aligned in [111] was 42 %. On the other hand, we changed the surface condition of N-terminated (111) diamond by thermal annealing. Then, we grew 10 nm diamond film on the surface. As a result, the probability of NV ensemble being aligned in [111] rose to 60 %. Also, s-factor developed from 0.44 to 0.52. |
