The plausible radial deformation of an individual SWNT under hydrostatic pressure is predicted using the method developed in the previous work [M. Hasegawa and K. Nishidate, Phys. Rev. B 74, 115401 (2006)]. It is found by ab initio electronic-structure calculations that the band gap of zigzag SWNTs is dictated by the shape of the high-curvature edge region of a deformed cross section perpendicular to the tube axis: If we let Rmin be an averaged curvature radius in that region, the band gap at the Γ point remains almost unchanged when Rmin≥3.2Å , and its closure occurs at Rmin≈2.4Å irrespective of tube size and cross-sectional shape as a whole. It is also confirmed that the band gap closure is accompanied by the concentration, in the high-curvature region, of the lowest conduction state at the Γ point. Possible implications of these results are discussed.","subitem_description_type":"Other"}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_16_relation_26":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.78.195403","subitem_relation_type_select":"DOI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©2008 The American Physical Society"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1098-0121","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"Department of Electrical and Electronic Engineering"},{"subitem_text_value":"Department of Materials Science and Engineering"}]},"item_16_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nishidate, Kazume"}],"nameIdentifiers":[{"nameIdentifier":"74027","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasegawa, Masayuki"}],"nameIdentifiers":[{"nameIdentifier":"74028","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"prb-v78i19p195403.pdf","filesize":[{"value":"511.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"prb-v78i19p195403.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9683/files/prb-v78i19p195403.pdf"},"version_id":"7bfcc705-cc7f-4b97-ad5d-3dd5dbad5bd2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ab initio calculations","subitem_subject_scheme":"Other"},{"subitem_subject":"carbon nanotubes","subitem_subject_scheme":"Other"},{"subitem_subject":"conduction bands","subitem_subject_scheme":"Other"},{"subitem_subject":"deformation","subitem_subject_scheme":"Other"},{"subitem_subject":"energy gap","subitem_subject_scheme":"Other"},{"subitem_subject":"semiconductor nanotubes","subitem_subject_scheme":"Other"}]},"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":"Universal band gap modulation by radial deformation in semiconductor single-walled carbon nanotubes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Universal band gap modulation by radial deformation in semiconductor single-walled carbon nanotubes"}]},"item_type_id":"16","owner":"3","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-01-09"},"publish_date":"2009-01-09","publish_status":"0","recid":"9683","relation_version_is_last":true,"title":["Universal band gap modulation by radial deformation in semiconductor single-walled carbon nanotubes"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T10:59:32.187819+00:00"}
