Clean‐Lifting Transfer of Large‐area Residual‐Free Graphene Films

Abstract
A unique “clean-lifting transfer” (CLT) technique that applies a controllable electrostatic force to transfer large-area and high-quality CVD-grown graphene onto various rigid or flexible substrates is reported. The CLT technique without using any organic support or adhesives can produce residual-free graphene films with large-area processability, and has great potential for future industrial production of graphene-based electronics or optoelectronics.
