Self‐supporting graphene films and their applications

Abstract: The self-supporting monolayer material which is graphene has excited enormous interest over the ten years since its discovery due to its remarkable electrical, mechanical thermal and chemical properties. In this paper we describe our work to develop chemical vapour deposition methods to grow monolayer graphene on copper foil substrates and the subsequent transfer process. Raman microscopy, scanning electron microscopy and atomic force microscopy (AFM) are used to examine the quality of the transferred material… Show more

“…The open question in the literature about the tractability of these types of materials could be partially solved by applying this approach. , The presented results point to this latter remark: By modifying the synthesis conditions or the substrate geometry, the twist angle of the stacked graphene layers could be tailored. These findings could be of enormous interest for some emerging graphene applications, since the identification of the relationship between stacking rotations and electronic or optic properties is a particularly intriguing subject in the case of few-layer graphene structures. Graphene self-supported membranes are being recently applied as mechanical resonators in graphene drums. The remarkable resilience of few-layer graphene membranes over microns of distance is expected to provide exceptional sensors for mass detection of single molecules. Nevertheless, understanding and mastering the mechanical and coupling properties of this type of bidimensional layered membranes are of great importance for better design, fabrication, and usage of the devices using them …”

“…This translates into ballistic transport on submicron scales. The roomtemperature mobility is limited by impurities or corrugations of the graphene surface, which means that it can still be improved significantly up to the order of 105 cm 2 /Vs [14,15].…”

“…Fig. 12 shows scanning electron microscopy (SEM) and atomic force microscopy (AFM) of the graphene based device reported in the literature as having the highest electron mobility to date [14]. The graphene film was obtained by mechanical exfoliation of graphite on Si/SiO 2 substrate in which the oxide layer below the graphene was etched in order to obtain a free-standing graphene flake connecting the metal electrodes.…”

“…Multilayer (3 -8 layers) CVD graphene on Ni was used for the suspended graphene experiments. The recipe for the graphene transfer process uses a PMMA supporting layer as reported in [21,22]. Ni is etched in 3 HPO 4 : 3 HNO 3 : 1 CH 3 COOH : 1 H 2 O.…”
