Description générale

Graphene is a unique one atom thick, two dimensional allotrope of carbon. Among all the synthesis techniques, chemical vapor deposition of graphene on copper foil is the most promising route for the large scale production of good quality graphene. Catalytic decomposition of hydrocarbons over copper foil renders monolayer graphene. Graphene deposits as a continuous polycrystalline sheet of individual graphene grains joined at grain boundaries. The epitaxial relationship between graphene and copper foil has been reported. Large uniform graphene domains may be accountable to the large grain size growth which results because of the low carbon solubility of copper and close melting point of copper and graphene growth temperatures.
Growth Method: CVD synthesis
Transfer Method: Clean transfer method
Quality Control: Optical Microscopy & Raman checked

Application

Graphene may be extensively incorporated in several applications, such as; nanoelectronics, fuel cells, solar cell, photovoltaic devices, in biosensing, optical biosensors, MEMS, NEMS, field effect transistors (FETs), chemical sensors, nanocarriers in biosensing assays.
