Abstract
In this paper, we use graphene as conductive layer to improve the field emission properties of CNTs. The metallic nature of graphene and its low contact resistance with metal electrode give a small voltage drop both along the graphene and at the graphene/metal interface. This means that the supply of electrons from the electrode to the emitters is sufficient.
