n silicon dioxide on a silicon wafe r in a process sometimes called micromechanical cleavage or, simply, the Scotch tape technique. Since 2004, an explosion in the investigation of graphene in term of synthesis, characterization, properties as well as specifical potential application were report ed. Preparation and characterization graphene Preparation methods Top-down approach (From graphite) Bottom up approach (from carbon precursors) - By chemical vapour deposition (CVD) of hydrocarbon - By epitaxial growth on electrically insulating surfaces such as SiC - anic Synthesis - Micromechanical exfoliation of graphite (Scotch t ape or peel-off method) - Creation of colloidal suspensions from graphite o xide or graphite pounds (GICs ) Ref: Carbon, 4 8, 2 1 2 7 – 2 1 5 0 ( 2 0 1 0 )
