摘要：
Photon-assisted electron transport for resonant tunneling has been investigated by using a current formula developed based on the nonequilibrium Green's function technique. We have studied the external frequency dependence as well as the energy level position dependence for the resonant ac tunneling through the quantum dot coupled to two superconducting reservoirs.
