▎ 摘　　要

We studied the transport properties of charge carriers in monolayer graphene-based barrier structures with Terahertz wave fields. The angularly averaged conductivity, shot noise, and Fano factor of the system have been calculated and analyzed as the external field strength, incident energy and the barrier width are changed. We find that they are improved and show peculiar behavior, due to the presence of external field. One can control the transport of carriers by adjusting the external field strength and the structure parameters of the system.
