Polaron effect on ballistic transport in armchair graphene nanoribbon

Graphene nanoribbon has altered the perspective of future electronics device industries. Post silicon based technology, Graphene nanoribbon is now considered the most promoting materials for the next generation electronics. Armchair graphene nanoribbon is one of two prototypes of graphene which is widely known for its semiconducting properties limited by width length below 50nm. However, some of the shortcoming of potential application remain obscure to expound. Here we investigate the ballistic transport performance of armchair graphene nanoribbon and the potential disturbance of polaron. Photon excitation with incorporating lower bandgap in armchair graphene tends to develop polaron. Through the generation of polaron due to the temperature variation, two dimensional armchair nanoribbon no longer respond as ballistic media to transport carriers. It has been found that the mean free path and mobility performance of carriers are affected due to the polaron effect.
