Templated growth of graphene: A novel method for efficient graphene synthesis

[摘要] A novel templated growth process for graphene structures is proposed and demonstrated. Extended, pristine sheets of graphene can be synthesized by additively reacting carbon into a pre-existing graphene sheet which is on a templating substrate through a CVD type process termed ;;van der Waals templating;;. Finding a technologically viable synthesis method for planar graphene has recently become of significant interest with the recent recognition of its unusual electronic properties. Various morphological growth patterns such as ;;pacman;; structures and rounded corners are observed which elucidate interesting features of this growth mechanism, linear sheet growths on the order of 150 nm have been produced.
