Pyroelectric measurements clarify switchable spontaneous polarization in polycrystalline C1\u2212xSxAW, whose polarization values are on the order of 10^\u22122\u2009\u2009\u03bcC/cm^2 at room temperature. A weak anomaly in the dielectric permittivity at temperatures near the ferroelectric transition temperature suggests improper ferroelectricity of C1\u2212xSxAW for all investigated values of x. A comprehensive study involving synchrotron x-ray powder diffraction measurements, molecular dynamics simulations, and first-principles calculations clarifies that the ferroelectric phase transition of C1\u2212xSxAW is driven by the freezing of the fluctuations of WO4 tetrahedra in the voids of an [AlO2]12^12\u2212 framework. The voltage response and electromechanical coupling factor of C1\u2212xSxAW estimated from the present results indicate that this material exhibits excellent performance as a pyroelectric energy harvester, suggesting that aluminate sodalites exhibit great promise as a class of materials for highly efficient energy-harvesting devices.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "http://doi.org/10.1103/PhysRevApplied.7.034012"}, {"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/26772"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2017 American Physical Society"}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2331-7019", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Maeda, Yusaku"}], "nameIdentifiers": [{"nameIdentifier": "72653", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Wakamatsu, Toru"}], "nameIdentifiers": [{"nameIdentifier": "72654", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Konishi, Ayako"}], "nameIdentifiers": [{"nameIdentifier": "72655", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Moriwake, Hiroki"}], "nameIdentifiers": [{"nameIdentifier": "72656", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Moriyoshi, Chikako"}], "nameIdentifiers": [{"nameIdentifier": "72657", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kuroiwa, Yoshihiro"}], "nameIdentifiers": [{"nameIdentifier": "72658", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tanabe, Kenji"}], "nameIdentifiers": [{"nameIdentifier": "72659", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Terasaki, Ichiro"}], "nameIdentifiers": [{"nameIdentifier": "72660", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Taniguchi, Hiroki"}], "nameIdentifiers": [{"nameIdentifier": "72661", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "PhysRevApplied7.pdf", "filesize": [{"value": "4.8 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 4800000.0, "url": {"label": "PhysRevApplied7.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/24550/files/PhysRevApplied7.pdf"}, "version_id": "c1514700-f579-4eab-8e02-60ccb4c3aaa2"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Improper Ferroelectricity in Stuffed Aluminate Sodalites for Pyroelectric Energy Harvesting", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Improper Ferroelectricity in Stuffed Aluminate Sodalites for Pyroelectric Energy Harvesting"}]}, "item_type_id": "10", "owner": "1", "path": ["336/695/696"], "permalink_uri": "http://hdl.handle.net/2237/26772", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2017-07-05"}, "publish_date": "2017-07-05", "publish_status": "0", "recid": "24550", "relation": {}, "relation_version_is_last": true, "title": ["Improper Ferroelectricity in Stuffed Aluminate Sodalites for Pyroelectric Energy Harvesting"], "weko_shared_id": null}
