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.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.105.165201","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://journals.aps.org/prb/abstract/10.1103/PhysRevB.105.165201","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1098-0121","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Umeda, T."}],"nameIdentifiers":[{"nameIdentifier":"1047299","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, K."}],"nameIdentifiers":[{"nameIdentifier":"1047300","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hara, H."}],"nameIdentifiers":[{"nameIdentifier":"1047301","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sumiya, H."}],"nameIdentifiers":[{"nameIdentifier":"1047302","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shinobu, Onoda"}],"nameIdentifiers":[{"nameIdentifier":"1047303","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uedono, A."}],"nameIdentifiers":[{"nameIdentifier":"1047304","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Chuprina, I."}],"nameIdentifiers":[{"nameIdentifier":"1047305","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Siyushev, P."}],"nameIdentifiers":[{"nameIdentifier":"1047306","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jelezko, F."}],"nameIdentifiers":[{"nameIdentifier":"1047307","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wrachtrup, J."}],"nameIdentifiers":[{"nameIdentifier":"1047308","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Isoya, J."}],"nameIdentifiers":[{"nameIdentifier":"1047309","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shinobu, Onoda","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1047310","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Negatively charged boron vacancy center in diamond","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Negatively charged boron vacancy center in diamond"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-03-24"},"publish_date":"2022-03-24","publish_status":"0","recid":"85697","relation_version_is_last":true,"title":["Negatively charged boron vacancy center in diamond"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T17:12:54.277353+00:00"}
