Abstract

A multilayer graphene composite comprising a plurality of stacked graphene layers separated from one another by an ion gel, wherein the ion gel is intercalated between adjacent graphene layers such that ions within the ion gel are able to arrange themselves at the surfaces of the graphene layers to cause a detectable change in one or more of an electrical and optical property of the graphene layers when a gate voltage is applied to a gate electrode in proximity to the ion gel.
