Powder x-ray diffraction (XRD) data suggest that Zn and Ti dopants substitute in the rocksalt layer rather than in the CoO 2 layer for x ≤ 0.1 and y ≤ 0.1, respectively. In Zn and Ti single-doped samples for x ≤ 0.1 and y ≤ 0.1, ZT at room temperature increased with x and y through an increase in the absolute Seebeck coefficient despite a decrease in electrical conductivity. In Zn and Ti double-doped samples, minor phases other than the misfit oxides were observed at approximately x + y ≥ 0.1. At x ≤ 0.1 and y ≤ 0.1, double doping improved the thermoelectric properties. ZT at room temperature reached a maximum value of 0.035 at (x, y) = (0.1, 0.03).","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of Electronic Materials, 41(6), pp.1217-1221; 2012","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer New York"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s11664-012-1929-5","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2012 TMS."},{"subitem_rights":"The final publication is available at www.springerlink.com."}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03615235","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1543186X","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Morimura, Takao"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hasaka, Masayuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kondo, Shin-ichiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakashima, Hiromichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Maeda, Hisamitsu"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"JEM41_1217.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JEM41_1217.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/9560/files/JEM41_1217.pdf"},"version_id":"c8d805db-c53d-43fd-ab01-ac6a115c43d3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"dimensionless figure of merit","subitem_subject_scheme":"Other"},{"subitem_subject":"Harman method","subitem_subject_scheme":"Other"},{"subitem_subject":"high-resolution TEM","subitem_subject_scheme":"Other"},{"subitem_subject":"Seebeck coefficient","subitem_subject_scheme":"Other"},{"subitem_subject":"XRD-Rietveld method","subitem_subject_scheme":"Other"}]},"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":"Microstructures and Thermoelectric Properties of Sintered Ca3Co4O9-Based Oxide","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Microstructures and Thermoelectric Properties of Sintered Ca3Co4O9-Based Oxide"}]},"item_type_id":"2","owner":"2","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-01-09"},"publish_date":"2013-01-09","publish_status":"0","recid":"9560","relation_version_is_last":true,"title":["Microstructures and Thermoelectric Properties of Sintered Ca3Co4O9-Based Oxide"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T01:42:53.759848+00:00"}
