We report a novel graphene transfer technique for fabricating graphene field-effect transistors (FETs) that avoids detrimental organic contamination on a graphene surface. Instead of using an organic supporting film like poly(methyl methacrylate) (PMMA) for graphene transfer, Au film is directly deposited on the as-grown graphene substrate. Graphene FETs fabricated using the established organic film transfer method are easily contaminated by organic residues, while Au film protects graphene channels from these contaminants. In addition, this method can also simplify the device fabrication process, as the Au film acts as an electrode. We successfully fabricated graphene FETs with a clean surface and improved electrical properties using this Au-assisted transfer method.

Abstract Objectives The main goal of this work is to achieve a direct transfer of graphene and examine the exact effect of surface tension (ST) on graphene during this type of transfer. Methods To reach this target, we designed a specific transfer container with two-sided ports to facilitate replacing liquids underneath graphene and monitor the effect of ST. We prepared liquids with various STs by mixing pure DI-water with different ratios of isopropanol (IPA). Results Our results indicate that high ST does not break the graphene structure if graphene has good quality. Besides, a surface tension gap (STG) can be applied to graphene at a specific level without damaging the graphene monolayer. Comparing those results to the defective graphene features after applying high ST and varied STGs confirms that standing high ST and STG can be considered a key feature of good quality graphene. Conclusion Thus, good quality graphene can be transferred at high ST (ST of water: 72 dyne/cm) with no sign of structural damage. In addition, this type of graphene can stand STG ≤ 40 dyne/cm. This new understanding of the ST effect on graphene could simplify the current direct transfer techniques and widen the graphene applications by expanding the choices of the target substrates and transfer liquids.
