Efficient inkjet printing of graphene

Abstract

An efficient and mature inkjet printing technology is introduced for mass production of coffee-ring-free patterns of high-quality graphene at high resolution (unmarked scale bars are 100 μm). Typically, several passes of printing and a simple baking allow fabricating a variety of good-performance electronic devices, including transparent conductors, embedded resistors, thin film transistors, and micro-supercapacitors.

Keywords: graphene; inkjet printing; micro-supercapacitors; thin film transistors; transparent conductors.
