In this study, we found a more positive potential for a lateral domain interface of p-n junction than for a conventional p-n junction. A terrace bilayer (TB) p-n junction of phthalocyanine (H2Pc) and 3,4,9,10-perylenetetracarboxylic-bis-benzimidazole (PTCBI) was studied using scanning Kelvin probe microscopy (SKPM), and its electronic properties were analyzed using the contact potential difference (V-CPD) data. The analysis of V-CPD in the single layer region and the bilayer region (BLR) indicated a vacuum level shift through the electron transfer from PTCBI into indium tin oxide (ITO), from H2Pc into ITO and from H2Pc into PTCBI. Furthermore, the comparison of these V-CPD data indicated a micrometer-localized positive potential in the boundary region (BDR) of the terrace bilayer structure of ptype on n-type. The gain difference of the V-CPD reached +0.1 V in comparison with the BLR. The phenomena can be explained as a lateral dipole at the p-n junction. Similar phenomena were observed in TB-H2Pc/C-60/ITO and TB-2Pc/PTCBI/Au. The gain was extracted as oxidation power in photoelectrochemistry; i.e., at -0.2 V vs. Ag/AgCl a greater anodic current was observed for a patterned terrace bilayer electrode. Additionally, as a photocatalyst film (i.e., a 2Pc (dot)/PTCBI/PTFE membrane filter), the p-n dot terrace structure showed a higher quantum efficiency (5.1%) than that of the bilayer (3.2%) for the decomposition of acetic acid. The present design and method were utilized to obtain an efficient photocatalyst, especially through the mitigation of potential loss from the photon energy to redox powers without changing the molecular component.","subitem_description_type":"Abstract"}]},"item_3_radio_42":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_radio_item":"Article"}]},"item_3_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/s41427-018-0058-x","subitem_relation_type_select":"DOI"}}]},"item_3_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1884-4057","subitem_source_identifier_type":"ISSN"}]},"item_3_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Laboratory for Chemistry and Life Science, Institute of Innovative Research Tokyo Institute of Technology"},{"subitem_text_value":"Laboratory for Chemistry and Life Science, Institute of Innovative Research Tokyo Institute of Technology"},{"subitem_text_value":"Department of Frontier Materials Chemistry, Graduate School of Science and Technology, Hirosaki University"},{"subitem_text_value":"Laboratory for Chemistry and Life Science, Institute of Innovative Research Tokyo Institute of Technology"}]},"item_3_version_type_18":{"attribute_name":"著者版フラグ","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":"Ahmad, Mohd Fairus"}],"nameIdentifiers":[{"nameIdentifier":"19658","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Motoya"}],"nameIdentifiers":[{"nameIdentifier":"19659","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Abe, Toshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"19657","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nagai, Keiji"}],"nameIdentifiers":[{"nameIdentifier":"19656","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-04"}],"displaytype":"detail","filename":"s41427-018-0058-x_2.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"s41427-018-0058-x_2","url":"https://hirosaki.repo.nii.ac.jp/record/5439/files/s41427-018-0058-x_2.pdf"},"version_id":"509f8623-814c-458f-8df3-cbdb1ad3b91a"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"Enhanced oxidation power in photoelectrocatalysis based on a micrometer-localized positive potential in a terrace hetero p-n junction","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Enhanced oxidation power in photoelectrocatalysis based on a micrometer-localized positive potential in a terrace hetero p-n junction"}]},"item_type_id":"3","owner":"11","path":["944"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-04"},"publish_date":"2019-03-04","publish_status":"0","recid":"5439","relation_version_is_last":true,"title":["Enhanced oxidation power in photoelectrocatalysis based on a micrometer-localized positive potential in a terrace hetero p-n junction"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-05-16T06:20:53.137380+00:00"}
