title: High responsivity, fast ultraviolet photodetector fabricated from ZnO nanoparticle-graphene core-shell structures.
abstract: We report a simple, efficient and versatile method for assembling metal oxide nanomaterial-graphene core-shell structures. An ultraviolet photodetector fabricated from the ZnO nanoparticle-graphene core-shell structures showed high responsivity and fast transient response, which are attributed to the improved carrier transport efficiency arising from graphene encapsulation.
