1- Cutting graphene on Cu foil ?
2- Cutting PMMA coated graphene on Cu foil ?
3- Cutting graphene after transfer on substrate?
Which technique can be true for this question and what can be the drawbacks of these situations?
Bryan Harry Rahmat Suryanto, Thank you for your consideration, but ı just want to wonder the cutting process of graphene. For example, you grow graphene on large area (2'' x 2'' )Cu foil via CVD then you want to dimensional adjustment (confine the size) like (1'' x 1''), so you have to cut it. I asked how can you achive this process without doing damage on graphene?
Cutting the graphene/Cu foil with clean scissors have generally worked fine for me, where I generally grow graphene on a large copper foil, and then cut into smaller 1X1 cm using a scissor (cleaned with Acetone). The conductivity seems to be the same over all my pieces.
