Zero-Dimensional Electrical Contact to a One-Dimensional Material

ORAL

Abstract

Recent work has shown that one-dimensional contacts can be made to two-dimensional graphene using boron nitride encapsulated graphene structures along with an etch process[1]. Here we report the encapsulation of carbon nanotubes, a one-dimensional material, between layers of boron nitride. By etching the edges we are able to use only the zero-dimensional ends of the carbon nanotubes to yield high-quality electrical contacts. This end-contact geometry along with an encapsulated nanotube provides possibilities for the realization of more complex nanotube heterostructure devices. [1]L.
