Transferring and Identification of Single- and Few-Layer Graphene on Arbitrary Substrates

Abstract: The transferring and identification of single- and few- layer graphene sheets from SiO2/Si substrates to other types of substrates is presented. Features across large areas (∼cm2) having single and few-layer graphene flakes, obtained by the microcleaving of highly oriented pyrolytic graphite (HOPG), can be transferred reliably. This method enables the fast localization of graphene sheets on substrates on which optical microscopy does not allow direct and fast visualization of the thin graphene sheets. No major… Show more

“…Their extreme thinness, down to a single layer, allows almost perfect electrostatic control of the transistor channel, making them robust to short channel effects and ideal for low power applications 8 . In addition, these materials offer excellent mechanical flexibility, optical transparency, and favorable transport properties for realizing electronic, sensing, and optical systems on arbitrary surfaces [9][10][11][12] . These thin, lightweight, bendable, highly rugged and low-power devices could bring dramatic changes to information processing, communications and human-electronic interaction.…”

“…(After each wet transfer, the sample was annealed for 30 min in air on a hot plate set to 300 C.) To transfer a thin crystal, a PMMA backing layer was spun onto the substrate hosting the exfoliated crystal. 6 The oxide was then etched in 2 M NaOH leaving the thin crystal attached to the PMMA floating in solution. After multiple dips in deionized water, the PMMA/thin crystal was positioned over its target using micromanipulators.…”
