Using soft transfer substrates and close conformal contact with the target substrate to minimize wrinkling and ripples. (a) Paraffin-mediated graphene transfer. The low softening/melting point of paraffin enables conformal coating of the graphene, minimizing wrinkles. Adapted under the terms of the Creative Commons Attribution 4.0 license from Ref. [117].
