Based on this, a simple tight-binding model with 5dε and 4f Γ8 orbitals on Yb atoms and the nearest neighbor σ-bonds between them is constructed with a good agreement to the above the LDA+U calculation near the gap. The density of states is also calculated and the shape is found to be very asymmetric with respect to the gap. A formation mechanism of the gap is clarified for the first time in a realistic situation with the orbital degeneracies in both conduction bands and the f states. This model can be a useful starting point for incorporating the strong correlation effect, and for understanding all the thermal, thermoelectric, transport and magnetic properties of YbB12.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"Copyright(c)2003 The Physical Society of Japan","subitem_description_type":"Other"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"Physical Society of Japan"}]},"item_119_relation_16":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1143/JPSJ.72.1131","subitem_relation_type_select":"DOI"}}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[著者版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Saso, Tetsuro"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1001026"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Saitama University, Graduate School of Science and Engineering"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2003"}]},"item_119_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐宗, 哲郎"},{"creatorName":"サソウ, テツロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Harima, Hisatomo"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1001026.pdf","filesize":[{"value":"402.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1001026.pdf","url":"https://sucra.repo.nii.ac.jp/record/12485/files/A1001026.pdf"},"version_id":"76124736-1080-4524-a533-bee18e82da88"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"hybridization gap","subitem_subject_scheme":"Other"},{"subitem_subject":"Kondo insulator","subitem_subject_scheme":"Other"},{"subitem_subject":"mixing","subitem_subject_scheme":"Other"},{"subitem_subject":"Tight-binding model","subitem_subject_scheme":"Other"},{"subitem_subject":"LDA+U","subitem_subject_scheme":"Other"}]},"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":"Formation Mechanism of Hybridization Gap in Kondo Insulators based on a Realistic Band Model and Application to YbB_<12>","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Formation Mechanism of Hybridization Gap in Kondo Insulators based on a Realistic Band Model and Application to YbB_<12>"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-03-08"},"publish_date":"2007-03-08","publish_status":"0","recid":"12485","relation_version_is_last":true,"title":["Formation Mechanism of Hybridization Gap in Kondo Insulators based on a Realistic Band Model and Application to YbB_<12>"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T13:03:23.645385+00:00"}
