High Degree Reduction of Graphene Oxide toward a High Carrier Mobility

Abstract

Graphene: a monolayer sheet of graphite shows many attractive properties, which are expected to be applied to various devices. Development of a high throughput method has been required to realize the applications. Chemical exfoliation via graphene oxide (GO) has been considered one of the promising methods. However, the graphene reduced from GO showed poor crystallinity and mobility than that of mechanically exfoliated graphene. Many reduction methods have been investigated to obtain high mobility graphene from GO lately. In this review, we introduce a novel reduction method which we have developed to convert GO to graphene by explaining their advantages and some ‰aws to be solved.
