Graphene nanoribbon crossbar nanomesh

Graphene nanoribbon crossbars exhibit negative differential resistance. This nonlinear current-voltage response can be exploited in a nanomesh geometry for high-density logic or memory. A 2xN crossbar array can store 3
^N
states. Proof-of-principle of a high functional density architecture exploiting the non-linear dynamics of graphene nanoribbon crossbars in a nanomesh geometry is demonstrated.
