3D multilayer graphene oxide thin film platform for functional devices

This thesis aims to provide novel solutions to the challenges that lie in the preparation of high-quality graphene-based film with accurate control and find out a practical way to manufacture ultrathin and large scale graphene-based platform for photonics applications. The optical properties can be dynamically tuned by laser-reduction that offers more potential for device design and fabrication. By conformally coating the graphene-based material onto Si nanostructures, hybrid photovoltaic and integrated photonic devices are demonstrated with unprecedented properties. Such platform opens up new avenues for biomedical imaging and sensing, all-optical photonic chips, photovoltaic, aerospace photonics, optical microelectromechanical systems, and lab-on-chip devices.
