石墨烯是一种自支撑单层材料，由于其卓越的电学、机械、热学和化学性能，自发现以来的10年里引起了人们的极大兴趣。在这里，作者描述了他们开发化学气相沉积方法在铜箔衬底上生长单层石墨烯以及随后的转移过程的工作。用拉曼显微镜、扫描电子显微镜和原子力显微镜检查转移材料的质量。为了演示这一过程，他们还描述了转移到图案SiO2/Si衬底上，形成自由悬浮的石墨烯鼓。它们表现出有趣的机械特性，正在被作为纳米机械谐振器进行探索。
Graphene, a self-supporting monolayer, has excited enormous interest over the 10 years since its discovery due to its remarkable electrical, mechanical thermal and chemical properties. Here the authors describe the authors' work developing chemical vapour deposition methods to grow monolayer graphene on copper foil substrates and the subsequent transfer process. Raman microscopy, scanning electron microscopy and atomic force microscopy are used to examine the quality of the transferred material. To demonstrate the process, they also describe transfer onto patterned SiO2/Si substrate which forms free suspended graphene drums. These show interesting mechanical properties which are being explored as nanomechanical resonators.
