Mechanisms of graphene growth by chemical vapour deposition on transition metals

Graphene has become the focus of research recently due to its properties. Various methods have been proposed for the synthesis of graphene, and chemical vapour deposition (CVD) appears to be the most promising route for synthesising large-area graphene. Use of Ru, Ir, Ni, or Co lead to a segregation growth procedure, in which carbon dissolves into the bulk metals at a high temperature and segregates to form graphene after reaching the carbon...
