Graphene-based materials and devices for soft electronics and photonics

Abstract

Graphene, two-dimensional one-atom-thick planar sheet of carbon atoms densely packed in a honeycomb crystal lattice, has attracted attention due to its extraordinary electrical, optical, and thermal properties. In addition graphene’s outstanding tensile strength allows graphene-based electronic and photonic devices to be flexible, stretchable, and foldable. In this talk, we discuss a novel platform and architecture for the development of high-performance graphene-based flexible devices and components. We have reported flexible electronic devices based on graphene materials, i.e. field-effect transistors, gas sensors, and nonvolatile memory devices, in which versatile properties of graphene materials have been incorporated into a flexible electronic platform. Recently, we also have demonstrated the graphene-based plasmonic waveguide for high-performance optical interconnection in flexible optoelectronic devices. We conclude that graphene-based electronic and photonic devices have huge potential to be exploited further for development of next-generation human-friendly soft optoelectronic systems. ...
