英文摘要	A nonequilibrium green's-function formalism is employed to study the time-dependent transport through resonant-tunneling structures. with this formalism, we derive a time-dependent landauer-buttiker formula that guarantees current conservation and gauge invariance. furthermore, we apply the formula to calculate the response behaviors of the resonant-tunneling structures in the presence of rectangular-pulse and harmonic-modulation fields. the results show that the displacement current plays the role of retarding the tunneling current.
