We demonstrate that scCO_2 milling overcomes size-reduction limitations reported for conventional milling. XRD and TEM reveal nanograins with smaller average sizes (\u003c 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", "download_preview_message": "", "file_order": 0, "filename": "Atwa_2020_Appl._Phys._Express_13_067002.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "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"], "permalink_uri": "http://hdl.handle.net/20.500.12000/47206", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2020-11-12"}, "publish_date": "2020-11-12", "publish_status": "0", "recid": "2011219", "relation": {}, "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_shared_id": -1}
