Both samples possess long energy-relaxation times (1.5 ms for YTiO3 and 15 mu s for Si); therefore, it is possible to extract terahertz complex conductivities of photoinduced carriers under equilibrium. We observed highly contrasting behaviour-Drude conductivity in Si and localized conductivity possibly obeying the Jonscher law in YTiO3. The carrier number at the highest carrier-concentration layer in YTiO3 is estimated to be 0.015 per Ti site. Anisotropic conductivity of YTiO3 is determined. Our study indicates that localized carriers might play an important role in the incipient formation of photoinduced metallic phases in Mott insulators. In addition, this study shows that the transfer-matrix method is effective for extracting an optical constant of a sample with a spatially inhomogeneous carrier distribution.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing Ltd"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0953-8984","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA10672168","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"406224"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2007-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"40","bibliographicPageStart":"406224","bibliographicVolumeNumber":"19","bibliographic_titles":[{"bibliographic_title":"Journal of Physics-Condensed Matter"},{"bibliographic_title":"Journal of Physics-Condensed Matter"}]}]},"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_version_resource":"http://purl.org/coar/version/c_b1a7d7d4d402bcce","subitem_version_type":"AO"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/0953-8984/19/40/406224","subitem_relation_type_select":"DOI"}},{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1088/0953-8984/19/40/406224","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"JPhys_19_406224.pdf","filesize":[{"value":"924.3 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2007514/files/JPhys_19_406224.pdf"},"version_id":"10df5cbc-2a90-406f-82fd-8487d0ed8514"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"21461"},"item_title":"Terahertz conductivity of localized photoinduced carriers in a Mott insulator YTiO3 at low excitation density, contrasted with the metallic nature in a band semiconductor Si","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2007514","relation_version_is_last":true,"title":["Terahertz conductivity of localized photoinduced carriers in a Mott insulator YTiO3 at low excitation density, contrasted with the metallic nature in a band semiconductor Si"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-21T10:07:17.971017+00:00"}
