The thicknesses and chemical states of the layers were determined by X-ray photoelectron spectroscopy (XPS) and near-edge X-ray fine structure (NEXAFS) around the phosphorus (P) and sulfur (S) K-edges, then the sample was irradiated with synchrotron soft X-rays. The chemical state of the OGN molecules before and after irradiation was examined by NEXAFS around the nitrogen (N) K-edge region.\nResults: The thickness of the MPTS-OGN layer was approximately 7.7 nm. The S atom of the OGN molecules was located at the bottom of the OGN layer. The peak shape of the N K-edge NEXAFS spectra of the MPTS-OGN layers clearly changed following irradiation.\nConclusions:The MPTS-OGN layer formed on the sapphire surface, and the chemical states and the structure of the interface were elucidated using synchrotron soft X-rays. The OGN molecules adsorbed on the MPTS films decomposed upon exposure to soft X-ray irradiation.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Taylor & Francis"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1080/09553002.2016.1179812 ","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0955-3002","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"成田あゆみ（物質材料研究機構）"}],"nameIdentifiers":[{"nameIdentifier":"478907","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤井, 健太郎"}],"nameIdentifiers":[{"nameIdentifier":"478908","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"馬場, 祐治（日本原子力研究開発機構）"}],"nameIdentifiers":[{"nameIdentifier":"478909","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"下山, 巌"}],"nameIdentifiers":[{"nameIdentifier":"478910","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤井 健太郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"478911","nameIdentifierScheme":"WEKO"}]}]},"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":"Use of a DNA film on a self-assembled monolayer for investigating the physical process of DNA damage induced by core electron ionization","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Use of a DNA film on a self-assembled monolayer for investigating the physical process of DNA damage induced by core electron ionization"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-20"},"publish_date":"2017-04-20","publish_status":"0","recid":"47728","relation_version_is_last":true,"title":["Use of a DNA film on a self-assembled monolayer for investigating the physical process of DNA damage induced by core electron ionization"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:36:11.869918+00:00"}
