We demonstrate that scCO_2 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 scCO_2 milled case. scCO_2 milling also preserves the crystallinity and shows less oxidation than conventional milling. This is the first report of Bi_2Te_3 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 Bi_2Te_3-based thermoelectric materials.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"en","subitem_1522300316516":"Japan Society of Applied Physics"},{"subitem_1522300295150":"ja","subitem_1522300316516":"公益社団法人応用物理学会"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/47206"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1882-0778"},{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1882-0786"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"en","subitem_1522650091861":"Applied Physics Express"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2020-05-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"067002-1","bibliographicPageStart":"067002-5","bibliographicVolumeNumber":"13"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_1522306287251":{"subitem_1522306382014":"DOI","subitem_1522306436033":"https://doi.org/10.35848/1882-0786/ab91d2"}},{"subitem_1522306287251":{"subitem_1522306382014":"DOI","subitem_1522306436033":"https://doi.org/10.35848/1882-0786/ab91d2"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"Atwa_2020_Appl._Phys._Express_13_067002.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2011219/files/Atwa_2020_Appl._Phys._Express_13_067002.pdf"},"version_id":"8affd36c-e590-4772-a484-6ea486d7b8fb"}]},"item_title":"Top-down approach using supercritical carbon dioxide ball milling for producing sub-10 nm Bi_2 Te_3 grains","item_type_id":"15","owner":"1","path":["1642838338003","1642838406414"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-11-12"},"publish_date":"2020-11-12","publish_status":"0","recid":"2011219","relation_version_is_last":true,"title":["Top-down approach using supercritical carbon dioxide ball milling for producing sub-10 nm Bi_2 Te_3 grains"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-08-03T05:29:08.956741+00:00"}
