Abstract
Graphene, with amazing physical and chemical properties, exhibits great potential for next-generation electronic devices. Promising achievements were obtained in recent years. Nevertheless, there are challenges before the industrialization of graphene-based electronic devices (G-EDs), which present opportunities as well. Mass-production of graphene and the growing G-EDs are the major issues. In this perspective, we briefly outline the notable advances in the production of graphene and the development of diverse G-EDs. Then we probe into the critical challenges on the way of G-EDs and provide corresponding strategies. Finally, we give our expectations of G-EDs in the near future.
Highlights
Graphene, the first two-dimensional material combining spectacular physical and chemical properties, displays great potential in electronic devices
Oxidation exfoliation of graphite was widely used to produce large-scale few-layer graphene oxides (GO) which was subsequently reduced to reduced graphene oxides (RGO)
By 2017, an annual production capability up to 10 00 000 m2 was realized by several companies and the wafer size of graphene on SiO2/Si or polyethylene terephthalate was as large as 100 × 100 cm2.16 The mobilities of as-fabricated graphene-based field-effect transistors (GFETs) exceeded 2000 cm2 V−1 s−1
Summary
Scitation.org/journal/apm especially high-performance devices, flaws or fluctuations need to be eliminated as much as possible. Scalable graphene films and flakes, including graphene oxides (GO) and reduced graphene oxides (RGO), are far from meeting the stringent requirement of uniformity and quality. As predicted by the company Mckinsey, the market for graphene semiconductors will reach $70 × 109 in 2030. Controllable mass-production of high-quality graphene is urgently needed, which plays a decisive role in commercialization. Purposive modification of graphene and an optimized processing technique of G-EDs are key issues for versatile devices. The cost and performance will deeply affect whether G-EDs can find its way to marketplace. These present challenges mean unprecedented opportunities for both researchers and industries
