Method of Preparation Graphene on Si/SiO2 Substrate was prepared by the following steps: |
| 1) Singlelayer graphene grown on copper foil |
| 2) Deposit PMMA and curing process |
| 3) Remove Cu by etching process |
| 4) Wash PMMA/Graphene in DI water |
| 5) Redeposit PMMA/Graphene onto Si substrate and curing process |
6) Remove PMMA with aceton Please contact us for quotes on larger quantities !!! |
