Study on the Diffusion Mechanism of Graphene Prepared by Chemical Vapor Deposition on Copper Substrates

Abstract

自2004年石墨烯被机械剥离出来,2010年获诺贝尔物理学奖以后,石墨烯毋庸置疑的成为了一名炙手可热的明星材料,各种围绕石墨烯的研究热潮席卷而来。抛开石墨烯的诺奖光环不谈,石墨烯确实有很多令人瞩目的性质,如高机械强度、高透光性、高载流子迁移率、高热导和化学稳定等等。性质决定用途,所以石墨烯在平板显示、电子器件、储能器件和生物医药等领域有很多潜在的应用等待探索开发。而实现这些美好应用愿景的前提,是制备高质量的石墨烯。在科研工作人员探索出的各种石墨烯制备方法中,铜基底上的化学气相沉积法(ChemicalVaporDeposition,CVD法),因其制备质量高、生长可控、制备简单且可转移至任意基底...Since graphene was produced by mechanically exfoliating graphite in 2004 and got the Nobel Prize in Physics in 2010, graphene undoubtedly has become a hot star material, and set off a variety of research interests. Despite the Nobel aura, graphene does have a lot of eye-catching properties, such as high strength, high transmittance, high carrier mobility, high thermal conductivity, chemical stabil...学位:理学博士院系专业:物理科学与技术学院_凝聚态物理学号:1982013015424
