The model used in this analysis describes the temperature dependence of the viscosity in terms of the mean bond strength E0, the mean coordination number Z0, and their fluctuations ΔE, ΔZ of the structural units that form the melt. The model reproduces quite well the temperature dependence of the viscosity of Cux(As2Se3)1−x observed experimentally. According to the theory, the fragility of the system increases as the fluctuation of the total bond strength increases. It is shown that the viscous flow is accompanied by the cooperative movements of the structural units and occurs by breaking selectively the weaker parts of the bonds between the structural units. This notion is related to the concept of Cooperatively Rearranging Region (CRR) in the theory of Adam–Gibbs. By analyzing the model, the fluctuation of the total bond strength in Cu–As–Se system is evaluated quantitatively, and the composition dependence of the fragility is discussed in terms of bond strength and the coordination number between the structural units. The analysis suggests that in the Cux(As2Se3)1−x system, there must be a strong composition dependence in the bond strength and a weak composition dependence in the fragility and coordination number fluctuation.","subitem_description_type":"Other"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier BV"}]},"item_16_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.ssi.2008.12.010","subitem_relation_type_select":"DOI"}}]},"item_16_relation_16":{"attribute_name":"情報源(ISSN)","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"01672738"}]}]},"item_16_relation_53":{"attribute_name":"著作の一部","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.elsevier.com/locate/ssi"}]}]},"item_16_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Elsevier B.V."}]},"item_16_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"420","subitem_subject_scheme":"NDC"}]},"item_16_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"725781 bytes"}]},"item_16_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"雑誌掲載論文"}]},"item_16_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_16_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_16_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"01"}]},"item_16_version_type_19":{"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":"Ikeda, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"97881","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aniya, Masaru"}],"nameIdentifiers":[{"nameIdentifier":"97882","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":"2020-03-02"}],"displaytype":"detail","filename":"Ikeda, Aniya SSI 180 _2009_ 522 Final Version .pdf","filesize":[{"value":"725.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Ikeda, Aniya SSI 180 _2009_ 522 Final Version .pdf","url":"https://kumadai.repo.nii.ac.jp/record/22503/files/Ikeda, Aniya SSI 180 _2009_ 522 Final Version .pdf"},"version_id":"0a9baa08-b1e8-49b8-b80d-abbac9178bd1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Chalcogenide glasses","subitem_subject_scheme":"Other"},{"subitem_subject":"Fragility","subitem_subject_scheme":"Other"},{"subitem_subject":"Viscosity","subitem_subject_scheme":"Other"},{"subitem_subject":"Cooperatively rearranging region","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A model for the temperature dependence of the viscosity in Cu–As–Se system","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A model for the temperature dependence of the viscosity in Cu–As–Se system"}]},"item_type_id":"16","owner":"1","path":["449"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-06-05"},"publish_date":"2009-06-05","publish_status":"0","recid":"22503","relation_version_is_last":true,"title":["A model for the temperature dependence of the viscosity in Cu–As–Se system"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-08-18T04:11:03.295401+00:00"}
