We demonstrate that scCO2 milling overcomes size-reduction limitations reported for conventional milling. XRD and TEM reveal nanograins with smaller average sizes (< 10 nm) and narrower grain size distributions in the scCO2 milled case. scCO2 milling also preserves the crystallinity and shows less oxidation than conventional milling. This is the first report of Bi2Te3 with a sub-10 nm grain size whilst conserving high quality crystallinity, made using a top-down approach. Our study offers a route for developing unprecedentedly fine bulk nanostructured Bi2Te3-based thermoelectric materials.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Japan Society of Applied Physics"},{"subitem_publisher":"IOP Publishing"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.35848/1882-0786/ab91d2","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://iopscience.iop.org/article/10.35848/1882-0786/ab91d2/meta","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2020 The Japan Society of Applied Physics"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882-0778","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"1882-0786","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-08-13"}],"displaytype":"detail","filename":"Atwa_2020_Appl._Phys._Express_13_067002.pdf","filesize":[{"value":"723.7 kB"}],"format":"application/pdf","license_note":"Creative Commons Attribution 4.0 International (https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Atwa_2020_Appl._Phys._Express_13_067002","url":"https://oist.repo.nii.ac.jp/record/1622/files/Atwa_2020_Appl._Phys._Express_13_067002.pdf"},"version_id":"d765fc7e-1803-4193-b07f-e57ee1a73954"}]},"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":"Top-down approach using supercritical carbon dioxide ball milling for producing sub-10 nm Bi2Te3 grains","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Top-down approach using supercritical carbon dioxide ball milling for producing sub-10 nm Bi2Te3 grains","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"28","path":["75","89"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-07-14"},"publish_date":"2020-07-14","publish_status":"0","recid":"1622","relation_version_is_last":true,"title":["Top-down approach using supercritical carbon dioxide ball milling for producing sub-10 nm Bi2Te3 grains"],"weko_creator_id":"28","weko_shared_id":28},"updated":"2023-06-26T11:46:30.660074+00:00"}
