AbstractWe report a theoretical analysis of parametric quantum pumping of electric current which is aided by quantum resonance. The electron pump is realized by cyclic deformations of the barrier heights of a double-barrier quantum well. The pumped current is found to have large values near a resonant level, it has a rather sensitive dependence on such control parameters as the deformation strength, phase difference, and the well width, and it has a power-law temperature dependence.
