Graphene on silicon dioxide (300nm)/Si wafer substrate was prepared by the following steps:1)As-grown Monolayer graphene on copper foil2)Deposite PMMA and Cure3)Etch away Cu4)Wash PMMA/Graphen in DI water5)Place PMMA/Graphen on substrate6)Redeposit PMMA and Cure7)Remove PMMA with acetone
Raman Spectrum for Graphene-SiO2
Graphene on water
Graphene transferred onto silicon dioxide substrate
Pretreated graphene: Graphene has been coated with PMMA
