Abstract
The influence of nonlinear time-dependent transport on charging effect s in small semiconducting quantum dots is studied. Due to absorption o r emission of energy quanta, additional resonant features are obtained in the Coulomb oscillations and the Coulomb staircase which might by accessible to experimental observation. For an AC-bias voltage the sys tem is shown to act like an electron pump whereas Ohm's law is obtaine d for strong time dependent coupling.
