A high-brightness large-diameter graphene coated point cathode field emission electron source
Traditional cold field emission electron sources rely on single crystal tungsten sharpened wires. Here, the authors use graphene-coated nickel point cathodes to devise alternative cold field emission electron sources for electron microscopy and lithography applications.
