| 内容記述 | Impurity-vacancy complexes in diamond are an attractive family of spin defects since NV−, SiV−, GeV−, and SnV− have emerged as promising platforms for quantum applications. Although boron is most easily incorporated into diamond, a boron-vacancy complex in the negative charge state (BV−) has eluded experimental observation. This center was theoretically predicted as another promising spin qubit. In this work, we experimentally observed an electron paramagnetic resonance (EPR) spectrum identified as BV− in synthetic diamonds via a Fermi-level tuning. Fingerprints of BV− such as the spin multiplicity of S= 1,C3v symmetry, the zero-field splitting (D= 2913 MHz), in addition to 10B and 11 B hyperfine (HF) interactions have been confirmed. Moreover, optically-pumped spin polarization has been observed with 3.0 to 3.6 eV excitation. However, unlike the NV− center, the photoluminescence as well as optically detected magnetic resonance from BV− has not been confirmed even at low temperatures. We speculate that the Jahn-Teller instability in the triplet states of the NV− and BV− centers results in different optical properties. | |||||
