Conductance Quantization in Graphene Nanoribbons

Abstract

We report the experimental observation of conductance quantization in graphene nanoribbons, where 1D transport subbands are formed due to the lateral quantum confinement. We show that this quantization in graphene nanoribbons can be observed at temperatures as high as 80 K and channel lengths as long as 1.7 $\mu$m. The observed quantization is in agreement with that predicted by theoretical calculations.
