Flexible Indium–Tin Oxide Crystal on Plastic Substrates Supported by Graphene Monolayer

Abstract Flexible and crystallized indium–tin oxide (ITO) thin films were successfully obtained on plastic polyethylene terephthalate (PET) films with monolayered graphene as a platform. The highly crystalline ITO (c-ITO) was first fabricated on a rigid substrate of graphene on copper foil and it wa...
