“…2d-f). 64 A similar exfoliation transfer using thermal release tape was developed by Caldwell et al 65 Holes approximately 10 mm in size were created during the transfer but the graphene showed a relatively small Raman D peak. Unlike the Raman studies, however, it was apparent from the comparison of before and after measurements of carrier density that the electrical properties were significantly decreased because of the holes and damage; the average mobility dropped from 1485 cm 2 V À1 s À1 to 201 cm 2 V À1 s À1 after the transfer.…”

The first micrometer-sized graphene flakes extracted from graphite demonstrated outstanding electrical, mechanical and chemical properties, but they were too small for practical applications. However, the recent advances in graphene synthesis and transfer techniques have enabled various macroscopic applications such as transparent electrodes for touch screens and light-emitting diodes (LEDs) and thin-film transistors for flexible electronics in particular. With such exciting potential, a great deal of effort has been put towards producing larger size graphene in the hopes of industrializing graphene production. Little less than a decade after the first discovery, graphene now can be synthesized up to 30 inches in its diagonal size using chemical vapour deposition methods. In making this possible, it was not only the advances in the synthesis techniques but also the transfer methods that deliver graphene onto target substrates without significant mechanical damage. In this article, the recent advancements in transferring graphene to arbitrary substrates will be extensively reviewed. The methods are categorized into mechanical exfoliation, polymer-assisted transfer, continuous transfer by roll-to-roll process, and transfer-free techniques including direct synthesis on insulating substrates.

“…The two-layer model was used to determine the thickness of graphene sheets grown epitaxially in multilayer stacks on SiC(0001) that were transferred layerby-layer to SiO 2 /Si substrates [28]. Figure 3.16 shows the high resolution C 1s spectra collected at one emission angle from the as-grown surface and the surface following the first and second transfer.…”

Binding energy scale calibration for XPS spectrometers was standardized as ISO 15472. The calibration of kinetic energy scale for AES spectrometers was standardized as ISO 17973 and 17974. The calibrations for the intensity scale are now discussing. The calibrations for the XPS and AES spectrometers were reviewed. The standard for XPS spectrometers specifies the calibration methods to estimate uncertainty with 95 reliability using repeatability and the linearity of binding energy scale and to correct the binding energy scales. This standard also specifies the method to establish the calibration schedule. Moreover, the standards on AES spectrometers specify the calibrations with high energy resolution for the chemical state analysis and the calibration with the medium energy resolution for elemental analysis.

The near explosion of attention given to graphene has attracted many to its research field. As new studies and findings about graphene synthesis, properties, electronic quality control, and possible applications simultaneous burgeon in the scientific community, it is quite hard to grasp the breadth of graphene history. At this stage, graphene's many fascinating qualities have been amply reported and its potential for various electronic applications are increasing, pulling in ever more newcomers to the field of graphene. Thus it has become important as a community to have an equal understanding of how this material was discovered, why it is stirring up the scientific community and what sort of progress has been made and for what purposes. Since the first discovery, the hype has expediently led to near accomplishment of industrial-sized production of graphene. This review covers the progress and development of synthesis and transfer techniques with an emphasis on the most recent technique of chemical vapor deposition, and explores the potential applications of graphene that are made possible with the improved synthesis and transfer.
