Techniques for the Dry Transfer of Epitaxial Graphene onto Arbitrary Substrates


Article Preview

Epitaxial graphene (EG) grown on the carbon-face of SiC has been shown to exhibit high carrier mobilities, in comparison to other growth techniques amenable to wafer-scale graphene fabrication. The transfer of large area (>mm2) graphene films to substrates amenable for specific applications is desirable. We demonstrate the dry transfer of EG from the C-face of 4H-SiC onto SiO2, GaN and Al2O3 substrates via two approaches using either 1) thermal release tape or 2) a spin-on, chemically-etchable dielectric. We will report on the impact that these transfer processes has upon the electrical properties of the transferred EG films.
