We found two Raman peaks at 75 and 101 cm-1 associated with the vibrations of guest I atoms inside the host Si cages, and observed some framework vibrations around 120–500 cm-1. These characteristic Raman bands and their pressure dependence are investigated in consideration of our recent Ba8Si46 studies. The lowest-frequency framework vibration at 133 cm-1 shows the softening with pressure, which seems to be the common feature of Si clathrates. A strong and broad Raman band centered at 461 cm-1 is identified to the highest-frequency framework vibration, which is likely intensified and broadened by the considerable framework distortion due to the replacement of framework Si with larger I atom. No obvious pressure-induced phase transition was found up to 28 GPa. The guest-host interactions are investigated by the present vibrational properties and are compared with those of previous neutron studies of I8Si44I2.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"AA11187113","subitem_source_identifier_type":"NCID"},{"subitem_source_identifier":"1098-0121","subitem_source_identifier_type":"ISSN"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"2121021"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2003-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"21","bibliographicPageStart":"2121021","bibliographicVolumeNumber":"68","bibliographic_titles":[{"bibliographic_title":"Physical Review B - Condensed Matter and Materials Physics"},{"bibliographic_title":"Physical Review B - Condensed Matter and Materials Physics"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevB.68.212102","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1103/PhysRevB.68.212102","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"PhysRevB_68_212102.pdf","filesize":[{"value":"62.9 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2008229/files/PhysRevB_68_212102.pdf"},"version_id":"c3db489d-3c4b-46f0-af6d-27130f90f3a5"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"16637"},"item_title":"High-pressure Raman study of the iodine-doped silicon clathrate I8Si44I2","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2008229","relation_version_is_last":true,"title":["High-pressure Raman study of the iodine-doped silicon clathrate I8Si44I2"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T03:22:55.191256+00:00"}
