Abstract

We propose to operate a locally-gated charge density wave as an electron pump. Applying an oscillating gate potential with frequency ff causes equally spaced plateaux in the sliding charge density wave current separated by ΔI=2eNf,\Delta I=2eNf, where NN is the number of parallel chains. The effects of thermal noise are investigated.
