Graphene, a single sheet of carbon with a honeycomb lattice, is a two-dimensional (2D) material whose high carrier mobility and carrier density tunable by a back gate [1–5] make it attractive for electronic device applications [6–13]. Large-area, good-quality graphene is commonly fabricated by chemical vapor deposition on metal substrates Graphene as a special two-dimensional material had several attractive properties such as high transparency (~98% in visible region for single-layer graphene), high carrier mobility (~200,000 cm 2 V −1 s −1 theoretically),, excellent flexibility and good chemical stability. A salient feature of our review is a critical comparison between carrier transport in graphene and in two-dimensional semiconductor systems (e.g. heterostructures, quantum wells, inversion layers) so that the unique features of graphene electronic properties arising from its gap- less, massless… Due to the importance of the electronics, most of the modern researches on solid state materials are focusing on their electronic properties.
