When builtin potential gradients are present in the quantum-well heterostructure due to variations in the In mole fraction (x) in the well, carriers that are thermally released by the particular well move unidirectionally from shallower to deeper wells. That is, asymmetric unidirectional motion of photoexcited carriers is possible via phonon-assisted activation above the barrier band-edge state. We have directly measured this perpendicular motion of photoexcited carriers by monitoring the transient PL signals from the different wells, which are spectrally separated. A rate equation analysis rigorously explains the dynamical changes of the PL signal intensities from the quantum wells as a function of lattice temperature. Our study of PL dynamics proves the asymmetric perpendicular flow of photoexcited carriers and the capture by the deeper quantum wells, providing firm evidence for the dynamical carrier flow and capture processes in the novel heterostructure.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_21_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"affiliations":[{"affiliationNames":[{"affiliationName":"","lang":"ja"}],"nameIdentifiers":[]}],"familyNames":[{"familyName":"Fujiwara","familyNameLang":"en"},{"familyName":"藤原","familyNameLang":"ja"},{"familyName":"フジワラ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kenzo","givenNameLang":"en"},{"givenName":"賢三","givenNameLang":"ja"},{"givenName":"ケンゾウ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1138","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90243980","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000090243980"},{"nameIdentifier":"7403468236","nameIdentifierScheme":"Scopus著者ID","nameIdentifierURI":"https://www.scopus.com/authid/detail.uri?authorId=7403468236"}],"names":[{"name":"Fujiwara, Kenzo","nameLang":"en"},{"name":"藤原, 賢三","nameLang":"ja"},{"name":"フジワラ, ケンゾウ","nameLang":"ja-Kana"}]}]},"item_21_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Published by the American Physical Society through the American Institute of Physics"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1103/PhysRevB.67.205322","subitem_relation_type_select":"DOI"}}]},"item_21_relation_14":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1103/PhysRevB.67.205322","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.aps.org/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.aps.org/","subitem_relation_type_select":"URI"}}]},"item_21_relation_66":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/120002440819","subitem_relation_type_select":"NAID"}}]},"item_21_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 2003 American Physical Society"}]},"item_21_select_59":{"attribute_name":"査読の有無","attribute_value_mlt":[{"subitem_select_item":"yes"}]},"item_21_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11187113","subitem_source_identifier_type":"NCID"}]},"item_21_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1098-0121","subitem_source_identifier_type":"ISSN"}]},"item_21_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"425","subitem_subject_scheme":"NDC"}]},"item_21_text_36":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Kyushu Institute of Technology, Tobata, Kitakyushu 804-8550, Japan"},{"subitem_text_value":"Kyushu Institute of Technology, Tobata, Kitakyushu 804-8550, Japan"},{"subitem_text_value":"Kyushu Institute of Technology, Tobata, Kitakyushu 804-8550, Japan"},{"subitem_text_value":"Crystal Fibre A/S, Blokken 84, DK-3460 Birkerend, Denmark"},{"subitem_text_value":"Research Center COM, Technical University of Denmark, Building 349, DK-2800 Kgs.
