Although a red-shift has been explained by a steady state model with the QD size distribution, carrier capture, relaxation, and re-trapping, a blue-shift could not be explained. The frequencies of height and diameter of QDs from an atomic force microscopy observation were investigated and calculated transition energies for each QD size. A calculated maximum frequency for GaAs QDs showed a good agreement with the obtained PL spectrum. Therefore, we concluded that the PL spectrum was caused by the ensemble of several size of QDs. The PL spectrum at 4 K could be decomposed into three peaks with a Gaussian function, corresponding to the large-, middle-, and small-size QDs, respectively. Although the integrated PL intensity for middle-size QDs was the largest up to 200 K, it suddenly decreased and those for middle- and small-size QDs became comparable. As a result, the PL energy as the ensemble of QDs moved to the higher energy side. We concluded that this caused the observed additional blue-shift of PL peak.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty of Engineering, University of Miyazaki","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00732558","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05404924","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"江添, 悠平","creatorNameLang":"ja"},{"creatorName":"エゾエ, ユウヘイ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"31477","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宮内, 雄大","creatorNameLang":"ja"},{"creatorName":"ミヤウチ, ユウダイ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"31478","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"間野, 高明","creatorNameLang":"ja"},{"creatorName":"マノ, タカアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"31479","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"碇, 哲雄","creatorNameLang":"ja"},{"creatorName":"イカリ, テツオ","creatorNameLang":"ja-Kana"},{"creatorName":"Ikari, Tetsuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"7290","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70113214","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70113214"}]},{"creatorNames":[{"creatorName":"福山, 敦彦","creatorNameLang":"ja"},{"creatorName":"フクヤマ, アツヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"Fukuyama, Atsuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"7289","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10264368","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=10264368"}]},{"creatorNames":[{"creatorName":"Ezoe, Yuhei","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"31482","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miyauchi, Yudai","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"31483","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mano, Takaaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"31484","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":"2020-06-21"}],"displaytype":"detail","filename":"51-54.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://miyazaki-u.repo.nii.ac.jp/record/5869.1/files/51-54.pdf"},"version_id":"109bea31-18f0-477a-a4f4-6bd21839c1e4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Quantum dots, GaAs, AlGaAs, Droplet epitaxy, Photoluminescence, Blue shift","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"液滴エピタキシー法により作製されたGaAs QDs のサイズが与えるフォトルミネッセンスの温度依存性への影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"液滴エピタキシー法により作製されたGaAs QDs のサイズが与えるフォトルミネッセンスの温度依存性への影響","subitem_title_language":"ja"},{"subitem_title":"Effect of Dot Size on the Temperature-Dependent Photoluminescence Signal in Droplet-Epitaxy-fabricated GaAs Quantum Dots","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"2","path":["36","73","329"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-06-21"},"publish_date":"2020-06-21","publish_status":"0","recid":"5869.1","relation_version_is_last":true,"title":["液滴エピタキシー法により作製されたGaAs QDs のサイズが与えるフォトルミネッセンスの温度依存性への影響"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-07-29T11:11:18.588715+00:00"}
