The obtained spin polarizations agreed with those expected from first-principles calculations considering the positron wave function and the electron density of states from the first surface layer to the vacuum region. The higher spin polarizations of graphene and h-BN on Co(0001) as compared to Ni(111) simply reflect the spin polarizations of these metals. The comparable spin polarizations of graphene and h-BN on the same metal are attributed to the creation of similar electronic states due to the strong influence of the metals: \nthe Dirac cone of graphene and the band gap of h-BN disappear as a consequence of d-π hybridization.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.97.195405","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://link.aps.org/doi/10.1103/PhysRevB.97.195405","subitem_relation_type_select":"URI"}}]},"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":"Miyashita, Atsumi"}],"nameIdentifiers":[{"nameIdentifier":"881151","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maekawa, Masaki"}],"nameIdentifiers":[{"nameIdentifier":"881152","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wada, Ken"}],"nameIdentifiers":[{"nameIdentifier":"881153","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawasuso, Atsuo"}],"nameIdentifiers":[{"nameIdentifier":"881154","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Takahiro"}],"nameIdentifiers":[{"nameIdentifier":"881155","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Entani, Shiro"}],"nameIdentifiers":[{"nameIdentifier":"881156","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakai, Seiji"}],"nameIdentifiers":[{"nameIdentifier":"881157","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miyashita, Atsumi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"881158","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maekawa, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"881159","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wada, Ken","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"881160","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawasuso, Atsuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"881161","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Takahiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"881162","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Entani, Shiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"881163","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakai, Seiji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"881164","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":"Spin polarization of graphene and $h$-BN on Co(0001) and Ni(111) observed by spin-polarized surface positronium spectroscopy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Spin polarization of graphene and $h$-BN on Co(0001) and Ni(111) observed by spin-polarized surface positronium spectroscopy"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-06"},"publish_date":"2018-05-06","publish_status":"0","recid":"48967","relation_version_is_last":true,"title":["Spin polarization of graphene and $h$-BN on Co(0001) and Ni(111) observed by spin-polarized surface positronium spectroscopy"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:40:47.909905+00:00"}
