▎ 摘　　要

NOVELTY - The method involves preparing a single nanometer scale groove structure for placing a carbon nano-tube on a substrate and locating the carbon nano-tube in the groove structure. The carbon nano-tube is educed by conductive materials. Graphene is transferred to an upper part of the groove structure of the carbon nano-tube with respect to air between the carbon nano-tube and the graphene in the groove structure. The conductive materials deposited on two ends of the graphene are educed. The substrate is made of silicon oxide, quartz, gallium arsenide or plastic. USE - Method for manufacturing a graphene transistor. ADVANTAGE - The method combines the carbon nano-tubes with the graphene to realize novel transistor with carbon structure. DETAILED DESCRIPTION - The conductive materials are selected from a metal material, a high doped semiconductor material, a conductive plastic or a polymer material. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene transistor.
