Multi-layer Graphene Growth from Solid Carbon Source Utilizing CVD Method

Recently, growth and investigation allotropes of carbon have received much attention. Graphene ,one ofthese allotropes, according to fairly strange electrical and optical properties, mechanical stiffness and extraordinarythermal conductivity noted by many researchers. In this paper we investigate how graphene grows from solid carbonsources by chemical vapor deposition (CVD) method on copper surface. after graphene grew on copper we transferredthese layers on silicon dioxide layer to investigate electrical and optical properties of them. These layers studied byRaman spectroscopy, scanning electron microscopy, atomic force microscopy and hall measurement aperture. Aftermaking ohmic contacts on these layers we investigated electrical properties of these layers.
