Annual-ring shaped graphene as a free-standing field emitter with high performance

Graphene oxide (GO) sheets were synthesized via a modified Hummer’s method. Subsequently, annual-ring shaped graphene hydrogel was formed through alkali-inducing hydrothermal process. The lyophilized GO hydrogel was tailored to a cylindrical emitter and demonstrated good field emission performance:...
