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.
