Pt has a large inverse spin Hall effect and is suitable as a spin current conversion layer. In the CoFeAl/carbon/Pt crossbar, the thermal spin current injection effect from the CoFeAl layer was observed by the Pt spin current conversion. Temperature dependence measurements were also performed. As future work, contribution and separation of the Nernst effect of the CoFeAl layer are necessary."}]},{"type":"significance_of_research_achievement","notation":[{"@language":"ja","@value":"スピンを利用したスピンゼーベック効果が発見された。しかし、熱伝導率の大きな無機材料を使用しているため、無駄に熱を伝えるため、発電効率が良くない。そこで、性能向上のため、有機をスピン伝導層として使用する有機スピンゼーベック素子を作成した。アモルスファスカーボンを使用した有機スピンゼーベック素子の測定により、アモルスファスカーボンのスピン緩和長が短いとことが分かった。有機スピンゼーベック素子の創成により、モバイルコンピューティングおよびユビキタス社会実現のために、温度差を利用した環境発電が期待される。"}]}],"researcher":[{"@id":"https://cir.nii.ac.jp/crid/1420564276161733760","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"30380562"},{"@type":"NRID","@value":"1000030380562"},{"@type":"ORCID","@value":"0000-0003-1427-3483"},{"@type":"NRID","@value":"9000239570924"},{"@type":"NRID","@value":"9000021084524"}],"foaf:name":[{"@language":"ja","@value":"山田 和正"},{"@language":"en","@value":"yamada kazumasa"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"九州大学"}],"role":"principal_investigator"}],"since":"2017-04-01","until":"2023-03-31","institution":[{"institutionIdentifier":[{"@type":"NII","@value":"0017102"}],"notation":[{"@language":"ja","@value":"九州大学"},{"@language":"en","@value":"Kyushu University"}]}],"fundingProgram":[{"jpcoar:funderName":[{"@language":"ja","@value":"科学研究費助成事業"},{"@language":"en","@value":"Grants-in-Aid for Scientific Research"}]},{"funderIdentifier":[{"@type":"CROSSREF","@value":"10.13039/501100001691"}],"jpcoar:funderName":[{"@language":"ja","@value":"科学研究費助成事業"}]}],"url":[{"@id":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-17K06303/","notation":[{"@value":"KAKEN"}]}],"createdAt":"2017-04-28","modifiedAt":"2025-11-19","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=%E5%BB%83%E7%86%B1%E5%88%A9%E7%94%A8","dc:title":"廃熱利用"},{"@id":"https://cir.nii.ac.jp/all?q=%E3%82%B9%E3%83%94%E3%83%B3","dc:title":"スピン"},{"@id":"https://cir.nii.ac.jp/all?q=%E6%9C%89%E6%A9%9F","dc:title":"有機"},{"@id":"https://cir.nii.ac.jp/all?q=%E3%82%AB%E3%83%BC%E3%83%9C%E3%83%B3","dc:title":"カーボン"},{"@id":"https://cir.nii.ac.jp/all?q=%E3%82%BC%E3%83%BC%E3%83%99%E3%83%83%E3%82%AF","dc:title":"ゼーベック"},{"@id":"https://cir.nii.ac.jp/all?q=%E7%86%B1%E9%9B%BB%E5%A4%89%E6%8F%9B","dc:title":"熱電変換"},{"@id":"https://cir.nii.ac.jp/all?q=%E3%82%B9%E3%83%94%E3%83%B3%E3%82%AE%E3%83%A3%E3%83%83%E3%83%97%E3%83%AC%E3%82%B9","dc:title":"スピンギャップレス"},{"@id":"https://cir.nii.ac.jp/all?q=%E3%83%8D%E3%83%AB%E3%83%B3%E3%82%B9%E3%83%88","dc:title":"ネルンスト"},{"@id":"https://cir.nii.ac.jp/all?q=%E3%82%B9%E3%83%94%E3%83%B3%E6%B5%81","dc:title":"スピン流"},{"@id":"https://cir.nii.ac.jp/all?q=%E6%8E%92%E7%86%B1%E5%88%A9%E7%94%A8","dc:title":"排熱利用"},{"@id":"https://cir.nii.ac.jp/all?q=%E5%B0%8E%E9%9B%BB%E6%80%A7%E9%AB%98%E5%88%86%E5%AD%90","dc:title":"導電性高分子"},{"@id":"https://cir.nii.ac.jp/all?q=%E5%86%8D%E7%94%9F%E5%8F%AF%E8%83%BD%E3%82%A8%E3%83%8D%E3%83%AB%E3%82%AE%E3%83%BC","dc:title":"再生可能エネルギー"},{"@id":"https://cir.nii.ac.jp/all?q=%E5%88%86%E5%AD%90%E6%80%A7%E5%9B%BA%E4%BD%93","dc:title":"分子性固体"},{"@id":"https://cir.nii.ac.jp/all?q=%E8%B6%85%E8%96%84%E8%86%9C","dc:title":"超薄膜"},{"@id":"https://cir.nii.ac.jp/all?q=%E6%9C%89%E6%A9%9F%E5%B0%8E%E4%BD%93","dc:title":"有機導体"}],"product":[{"@id":"https://cir.nii.ac.jp/crid/1050589221515772160","@type":"Article","resourceType":"学術雑誌論文(journal article)","productIdentifier":[{"@type":"HDL","@value":"https://hdl.handle.net/2324/7409284"},{"@type":"DOI","@value":"10.1016/j.synthmet.2018.11.019"},{"@type":"URI","@value":"https://api.elsevier.com/content/article/PII:S0379677918302777?httpAccept=text/xml"},{"@type":"URI","@value":"https://api.elsevier.com/content/article/PII:S0379677918302777?httpAccept=text/plain"},{"@type":"DOI","@value":"10.48550/arxiv.1808.08838"}],"notation":[{"@language":"en","@value":"Temperature dependence of mobility of conducting polymer polyaniline with secondary dopant"}]},{"@id":"https://cir.nii.ac.jp/crid/1010576118546188416","@type":"Article","resourceType":"学術雑誌論文(journal article)","notation":[{"@language":"ja","@value":"スピンギャップレス半導体の成膜とプレーナーホール効果"}]}],"dataSourceIdentifier":[{"@type":"KAKEN","@value":"17K06303"},{"@type":"IRDB","@value":"oai:irdb.nii.ac.jp:01211:0007321210_JGN_9GGrw6Tp7AaqsBRWVubwMhEtnaf"}],"grant":{"grantIdentifier":[{"@type":"NII","@value":"72"}],"jpcoar:fundingStream":[{"@language":"ja","@value":"基盤研究(C)"},{"@language":"en","@value":"Grant-in-Aid for Scientific Research (C)"}]},"allocationClassification":[{"notation":[{"@language":"ja","@value":"基金"},{"@language":"en","@value":"Multi-year Fund"}]}],"projectStatus":"project_closed","allocationAmount":{"totalCost":{"amount":"4420000","currency":"JPY"},"breakdownCost":[{"notation":[{"@language":"ja","@value":"直接経費"},{"@language":"en","@value":"Direct Cost"}],"amount":"3400000","currency":"JPY"},{"notation":[{"@language":"ja","@value":"間接経費"},{"@language":"en","@value":"Indirect Cost"}],"amount":"1020000","currency":"JPY"}]}}
