Abstract

In this work, we use electrolytic copper foils as substrates for the deposition of graphene by chemical vapor deposition. We investigate the effects of preannealing conditions, methane injection time, and temperature to synthesize graphene with a similar quality as when grown on cold-rolled copper. We find that the electrolytic copper foil’s annealing conditions and CH4 injection temperature determine the quality of graphene.

通过化学气相沉积比较电解铜箔和压延铜箔上石墨烯的特性和生长情况
在这项研究中,我们使用电解铜箔作为基底,通过化学气相沉积法沉积石墨烯。我们研究了预退火条件、甲烷注入时间和温度对合成石墨烯的影响,以获得与冷轧铜上生长的石墨烯相似的质量。我们发现,电解铜箔的退火条件和 CH4 注入温度决定了石墨烯的质量。
