PREPARING METHOD OF GRAPHENE, GRAPHENE SHHEET AND DEVICE USING THE SAME

摘要

PURPOSE: A method for manufacturing graphene, a graphene sheet, an element using the same are provided to simplify manufacturing processes by forming graphene on a substrate without a catalyst and omitting a process for eliminating a catalyst layer. CONSTITUTION: A method for manufacturing graphene forms graphene(20) on a substrate(12) by supplying heat and gas containing carbon source on the substrate to be reacted. The reaction is implemented at a temperature lower than or equal to 1000 degrees Celsius. The graphene is formed based on inductively coupled plasma-chemical vapor deposition, low pressure chemical vapor deposition, or atmospheric pressure chemical vapor deposition. The graphene is further cooled and patterned. The substrate is transparent and is patterned.
