Demystifies Conductivity of Ruthenate Nanosheets, Moving Towards Next-generation Electronics| MANAPrevious Index NextResearch Highlights[Vol. 82]Demystifies Conductivity of Ruthenate Nanosheets, Moving Towards Next-generation Electronics17 Feb, 2023A research team at MANA has shed light on how electrical conduction in oxide nanosheets canbe markedly affected by small changes in their atomic arrangement.The physical properties of a material are dictated by the arrangement of its atoms. This holds true notonly for classical three-dimensional crystals but also for two-dimensional structures such as atomicallythin nanosheets that are quickly becoming the cornerstone of many next-generation technologies.However, the detailed atomic arrangement of certain nanosheets has not been fully elucidated, whichlimits experts' understanding of the origin of their desirable properties. This problem is also encounteredwhen investigating ruthenate nanosheets, conductive oxides with promising applications in electronicsand energy storage.The mystery underlying the conduction mechanisms in ruthenate nanosheets motivated a team ofresearchers at MANA, led by Dr. Satoshi Tominaka, to further investigate their atomic structure. In arecent study, they analyzed how the possible structural symmetries in ruthenate nanosheets alteredtheir conducting properties.The researchers employed a pair distribution function (PDF), which described the probability of findingtwo atoms at a certain distance apart inside a material. Using PDF, they found that ruthenatenanosheets with the same atomic composition can adopt two different atomic arrangements, leading todifferences in their symmetry. "Although the structural difference was not large, symmetry changesresulted in remarkably different properties, with ruthenate nanosheets behaving either as a graphene-ResearchQuantum Materials FieldNanomaterials FieldResearch SupportResearch HighlightsHot TopicsHome  > Research  > Research Highlights  > Vol. 82 Demystifies Conductivity of Ru･･･About MANA Research People News Room Outreach Employment AlumniSite Map Contact Us Access to MANA Website System Requirements   Text size  Standard Large  Japanese Page2024/07/16 13:37 Demystifies Conductivity of Ruthenate Nanosheets, Moving Towards Next-generation Electronics| MANAhttps://www.nims.go.jp/mana/research/highlights/vol82.html 1/2https://www.nims.go.jp/mana/research/highlights/vol81.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttps://www.nims.go.jp/mana/research/highlights/vol83.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/research/quantum_material.htmlhttps://www.nims.go.jp/mana/research/nano_material.htmlhttps://www.nims.go.jp/mana/research/researcher_support.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttps://www.nims.go.jp/mana/research/hottopics/index.htmlhttps://www.nims.go.jp/mana/jp/index.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttp://www.jsps.go.jp/english/e-toplevel/http://www.jsps.go.jp/english/e-toplevel/https://www.nims.go.jp/mana/index.htmlhttps://www.nims.go.jp/mana/index.htmlhttps://www.nims.go.jp/mana/about/index.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/member/index.htmlhttps://www.nims.go.jp/mana/news_room/2024.htmlhttps://www.nims.go.jp/mana/pror/index.htmlhttps://www.nims.go.jp/mana/recruit/index.htmlhttps://www.nims.go.jp/mana/alumni/index.htmlhttps://www.nims.go.jp/mana/siteinfo/sitemap.htmlhttps://www.nims.go.jp/mana/siteinfo/inquiry.htmlhttps://www.nims.go.jp/mana/siteinfo/access.htmlhttps://www.nims.go.jp/mana/siteinfo/accessibility.htmlhttps://www.nims.go.jp/mana/jp/research/highlights/vol82.htmllike semimetal or a semiconductor as confirmed by our calculations," explains Dr. Tominaka. "Thishighlights the importance of symmetry analysis, even in low-dimensional materials."Overall, this study paves the way to a better understanding of oxide nanosheets, which could be a gamechanger in the development of future electronic and electrochemical devices.Reference“Symmetric Breakage-Induced Semimetallic State: Polymorphism in Ruthenate Nanosheets”Kazutaka Sonobe, Satoshi Tominaka, and Wataru Sugimoto.Journal: Journal of the American Chemical Society 2022, 144, 33, 15008–15012 (July 25, 2022)DOI : 10.1021/jacs.2c05951AffiliationsInternational Center for Materials Nanoarchitectonics (WPI-MANA), National Institute for MaterialsScience (NIMS), Namiki 1-1, Tsukuba, Ibaraki 305-0044, JapanContact informationResearch Center for Materials Nanoarchitectonics (MANA)National Institute for Materials Science1-1 Namiki, Tsukuba, Ibaraki 305-0044 JapanPhone: +81-29-860-4710E-mail: mana-pr[AT]nims.go.jpTo receive our e-mail newsletter “MANA Research Highlights”, please send an e-mail with "MANA ResearchHighlights request” in the subject line or main text to the following address: mana-pr_at_nims.go.jp *Pleasechange "_at_ " in the email address to @.Research Center for Materials Nanoarchitectonics (MANA)National Institute for Materials Science (NIMS)1-1 Namiki Tsukuba, Ibaraki 305-0044 JAPAN+81-29-860-4709E-mail: mana[AT]nims.go.jpCopyright © National Institute for Materials Science.
