At the 7-nm node and a Fermi energy of 0.3 eV, borophene exhibits an intrinsic MFP comparable to graphene and nearly three orders of magnitude higher than copper. Additionally, borophene achieves up to an 85.5% reduction in effective resistivity compared to copper, while maintaining competitive performance relative to graphene. These findings demonstrate that Fermi-energy tuning significantly enhances borophene’s transport performance, highlighting its strong potential as a scalable and energy-efficient on-chip interconnect material for advanced CMOS technologies.</div></div>","PeriodicalId":17219,"journal":{"name":"Journal of Science: Advanced Materials and Devices","volume":"11 1","pages":"Article 101092"},"PeriodicalIF":6.8,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146034360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
