With an increase in the Ar⁺-ion dose, coherent D-mode phonon appears at which the dephasing rate of the coherent G-mode phonon begins to increase. The increase in the amplitude of the coherent D-mode phonon and those in dephasing rates of the coherent D-mode and G-mode phonons indicate effective carrier-defect scatterings in the defective graphite. The dephasing rate of the D-mode is larger than that of the G-mode, indicating an existence of an additional dephasing process for the D-mode. We attribute it to the broad spectral distribution of the D-mode phonon, which is understood as a coherent excitation of large wavevector phonons with different wavevectors through inter-Dirac-cone scattering. The frequency chirping of the D-mode and its defect density dependence are also discussed based on this scattering mechanism.","subitem_description_type":"Abstract"}]},"item_2_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{},{}],"names":[{"name":"カタヤマ, イクフミ"}]},{"nameIdentifiers":[{}],"names":[{"name":"コガ, ショウ"}]},{"nameIdentifiers":[{},{}],"names":[{"name":"タケダ, ジュン"}]},{"nameIdentifiers":[{}],"names":[{"name":"ヒシタ, シュンイチ"}]},{"nameIdentifiers":[{}],"names":[{"name":"フジタ, ダイスケ"}]},{"nameIdentifiers":[{}],"names":[{"name":"キタジマ, マサヒロ"}]}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11556832","subitem_source_identifier_type":"NCID"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Engineering, Yokohama National University"},{"subitem_text_value":"Graduate School of Engineering, Yokohama National University"},{"subitem_text_value":"Graduate School of Engineering, Yokohama National University"},{"subitem_text_value":"Optical and Electronic Materials Unit, National Institute for Materials Science"},{"subitem_text_value":"Nano Characterization Unit, National Institute for Materials Science"},{"subitem_text_value":"Graduate School of Engineering, Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Katayama, Ikufumi"}],"nameIdentifiers":[{"nameIdentifier":"19618","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"80432532","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=80432532"}]},{"creatorNames":[{"creatorName":"Koga, Sho"}],"nameIdentifiers":[{"nameIdentifier":"19009","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takeda, Jun"}],"nameIdentifiers":[{"nameIdentifier":"9","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60202165","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=60202165"}]},{"creatorNames":[{"creatorName":"Hishita, Shunichi"}],"nameIdentifiers":[{"nameIdentifier":"19011","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujita, Daisuke"}],"nameIdentifiers":[{"nameIdentifier":"19012","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitajima, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"19013","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":"2016-09-16"}],"displaytype":"detail","filename":"JCSJ_121_291.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JCSJ_121_291.pdf","url":"https://ynu.repo.nii.ac.jp/record/4152/files/JCSJ_121_291.pdf"},"version_id":"63e56394-c271-4372-963c-aaadf7f39fd8"}]},"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":"Electron-phonon coupling and defect scatterings in Ar⁺-ion implanted graphite","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Electron-phonon coupling and defect scatterings in Ar⁺-ion implanted graphite"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-05-26"},"publish_date":"2014-05-26","publish_status":"0","recid":"4152","relation_version_is_last":true,"title":["Electron-phonon coupling and defect scatterings in Ar⁺-ion implanted graphite"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T19:27:53.425762+00:00"}
