The team demonstrated that the size and flexibility of Si\u2013O ring structures within the film vary with the substrate, enabling dramatic changes in thermal conductivity.<\/p>\n\n\n\n<p>This finding opens new possibilities for efficient thermal management in semiconductor devices and is expected to contribute to higher performance and energy-saving technologies in next-generation electronics.<\/p>\n\n\n\n<p>The research has been published in Nano Letters, a journal of the American Chemical Society, on April 14 at 4:00 PM (JST).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>https:\/\/www.linkedin.com\/feed\/update\/urn:li:activity:7317454021147926530\/ https:\/\/pubs.acs.org\/doi\/10.1021\/acs&#8230;..<\/p>\n","protected":false},"author":1,"featured_media":3815,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/posts\/3817"}],"collection":[{"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/comments?post=3817"}],"version-history":[{"count":1,"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/posts\/3817\/revisions"}],"predecessor-version":[{"id":3818,"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/posts\/3817\/revisions\/3818"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/media\/3815"}],"wp:attachment":[{"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/media?parent=3817"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/categories?post=3817"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/functfilm.es.hokudai.ac.jp\/english\/wp-json\/wp\/v2\/tags?post=3817"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
