The electronic resistivity of this molecular solid shows metal-to-insulator (MI) crossover behavior at TMI=50K. Our x-ray diffraction and 13C nuclear magnetic resonance experiments revealed that α−(BETS)2I3 maintains the inversion symmetry below TMI. First-principles calculations found a pair of anisotropic Dirac cones at a general k point, with the degenerate contact points at the Fermi level. The origin of the insulating state in this system is a small energy gap of ∼2meV opened by the spin-orbit interaction. The Z2 topological invariants indicate that this system is a weak topological insulator. Our results suggest that α−(BETS)2I3 is a promising material for studying the bulk Dirac electron system in two dimensions.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1103/PhysRevB.103.035135", "subitem_relation_type_select": "DOI"}}]}, "item_9_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2021 American Physical Society", "subitem_rights_language": "en"}]}, "item_9_source_id_7": {"attribute_name": "収録物識別子", "attribute_value_mlt": [{"subitem_source_identifier": "2469-9950", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Kitou, Shunsuke", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Tsumuraya, Takao", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Sawahata, Hikaru", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Ishii, Fumiyuki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Hiraki, Ko-ichi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Nakamura, Toshikazu", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Katayama, Naoyuki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Sawa, Hiroshi", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2021-10-15"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "PhysRevB_103_035135.pdf", "filesize": [{"value": "1.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 1600000.0, "url": {"objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/2001515/files/PhysRevB_103_035135.pdf"}, "version_id": "0bceb5bc-52fe-4953-873b-48a664732d32"}]}, "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": "Ambient-pressure Dirac electron system in the quasi-two-dimensional molecular conductor α−(BETS)2I3", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Ambient-pressure Dirac electron system in the quasi-two-dimensional molecular conductor α−(BETS)2I3", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "17", "path": ["322"], "permalink_uri": "http://hdl.handle.net/2237/0002001515", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2021-10-15"}, "publish_date": "2021-10-15", "publish_status": "0", "recid": "2001515", "relation": {}, "relation_version_is_last": true, "title": ["Ambient-pressure Dirac electron system in the quasi-two-dimensional molecular conductor α−(BETS)2I3"], "weko_shared_id": -1}
