Abstract :
Graphene transfer is critical for successful graphene-device integration. Even though multiple transfer approaches have been developed, an optimal solution is still not available. In this paper, we demonstrate dry transfer of graphene transfer Cu foil to polystyrene using mild heat and pressure. Two different printing systems are evaluated: a wafer bonder and a more cost-effective heat press. Chemical, morphological, structural and electrical characterization of the samples before and after transfer is performed. The results suggest that differences in the operation of the printing devices can be correlated to uniformity of transferred graphene. Regardless of the printing approach the surface resistivity of the polymer was decreased by 16 orders of magnitude.
