Abstract: Graphene, two dimensional (2D) carbon-carbon atoms arranged in a hexagonally honey‐ comb lattice structure, is the latest carbon (C) allotrope to be discovered. It has gained tremendous scientific research interests due to some unique properties, such as quantum hall effect and nearly ballistic electronic transportation in ambient.[1-4] These properties have stimulated intense activity among physicists, chemists and material scientists. Much research has focused on developing routs for the controllable growth of high quality graphene. Historically, graphene can be produced via micromechanical cleavage and SiC decomposition methods.[2, 5, 6] In order to meet even higher requirements, such as good crystallinity, less impurities and large area coverage, the present most successful fabrica‐ tion technique focuses on chemical vapor deposition (CVD) on copper [5 8] Some other graphene growth methods include growth of graphene from solid carbon source, gra‐ phene synthesis by ion beam implantation, and graphene formation by decomposition of C60, have also been reported in the recent years.[9, 10] Apart from these, pulsed laser deposition (PLD), which is one of the unique physical vapor deposition (PVD) methods, represents a completely new fabrication way in this field.
