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
## Abstract In this work, we study the effect of an applied ac gate voltage on the spin filtering and pumping properties of a lateral double quantum dot, in the Coulomb blockade and weak coupling regimes, considering not only the effect of the ac potential on the interβdot tunneling but also on the
We describe photon assisted tunneling (PAT) in single and coupled quantum dot systems which have a relatively large zero-dimensional (0D) level separation. A microwave electric field applied across the tunneling barrier leads to the formation of a sideband structure. For a single quantum dot system,
