Description 1141-1144
Graphene is a 2-dimensional flat sheet of carbon species confined into a honeycomb structure exhibits unique optical, electrical, thermal and mechanical properties. Graphene due to its fascinating properties finds application in the area of flexible electronics, nano-devices, health care, defence, photovoltaics and many others. In this work, graphene is grown on a copper foil using thermal chemical vapor deposition (CVD) at 1000 °C. Methane is used as a carbon source and hydrogen is supplied for the reduction of copper catalyst.Raman spectroscopy along with surface morphology and surface topology confirms the formation of graphene layer. Further, the fabricated graphene is directly transferred toglass substrate without any support layer. SEM and Raman confirms the defect-free transfer of graphene. Moreover, transferred graphene sheet shows high transparency along with hydrophobic nature with a contact angle of 93°.
