Abstract
We propose to operate a locally gated charge density wave as an electron pu mp. Applying an oscillating gate potential with frequency f causes equally spaced plateaus in the sliding charge density wave current separated by Del ta I=2eNf, where N is the number of parallel chains. The effects of thermal noise are investigated. (C) 1999 American Institute of Physics. [S0003-695 1(99)00133-3].
