SYNTHESES OF LARGE-SIZED SINGLE CRYSTAL GRAPHENE: A REVIEW OF RECENT DEVELOPMENTS

Single crystal graphene has been getting lots of attention due to the lack of grain boundaries which ensures its distinguished intrinsic properties and good performance in graphene-based devices. Hence, the realization of single crystal graphene growth with tunable size and high crystallinity will be of great importance in commercial production and widespread applications. Recently, numerous studies have focussed on the controlled single crystal graphene growth, and great advancements have been made in the synthesis of large-sized single-crystal graphene (LSSG) by chemical vapor deposition (CVD). In this review, current developments of CVD-grown LSSG and its future prospects are presented and discussed. We emphasize on growth methods and growth mechanisms over transition-metal Cu and Cu alloys for deeper insights in control of size and crystallinity.
