Reduction of charge transfer region using graphene nano-ribbon geometry for improved complementary FET performance at sub-micron channel length

In this work, we investigate the effect of nano-ribbon geometries on graphene device performance and explain its effect on reducing the negative impact of Dirac point shift due to charge transfer into the graphene channel from the metal-graphene contact thereby leading to improved device performance and balanced n, p FET performance at submicron channel lengths.
