These systems have a superconducting transition temperature Tc of around 100K even under normal pressure, which is very interesting because it is close to the transition temperature observed in the well-known copper oxide system. These systems show superconductivity even in the bulk state, but their Tc is less than 10K, and it is highly possible that the Tc is greatly increased by the surface and interface effects. Therefore, we hypothesized that the essence of these superconducting mechanisms might be expressed by the mutual cooperation of phonons and electron correlations, and examined them by first-principles calculations. These results have been compiled and published as a paper.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2019年度～2022年度科学研究費補助金(基盤研究(C))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"19K03716","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"item_8_text_65","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"出版タイプ","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":"佐野, 和博","creatorNameLang":"ja"},{"creatorName":"Sano, Kazuhiro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"大野, 義章","creatorNameLang":"ja"},{"creatorName":"Ono, Yoshiaki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"中村, 浩次","creatorNameLang":"ja"},{"creatorName":"Nakamura, Kohji","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":"2024-10-24"}],"filename":"2024RP0082.pdf","filesize":[{"value":"178 KB"}],"format":"application/pdf","url":{"label":"2024RP0082.pdf","url":"https://mie-u.repo.nii.ac.jp/record/2000992/files/2024RP0082.pdf"},"version_id":"3d84bbb4-5db7-4c66-8337-453d5fd38301"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"超伝導","subitem_subject_scheme":"Other"},{"subitem_subject":"第一原理計算","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"第一原理計算による表面・界面系での高温超伝導","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"第一原理計算による表面・界面系での高温超伝導","subitem_title_language":"ja"},{"subitem_title":"High-temperature superconductivity in surface/interface systems by first-principles calculations","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1728958155548"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-10-24"},"publish_date":"2024-10-24","publish_status":"0","recid":"2000992","relation_version_is_last":true,"title":["第一原理計算による表面・界面系での高温超伝導"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-10-24T04:55:40.534413+00:00"}
