Steady-state theory of current transfer

Abstract

Current transfer is defined as a charge-transfer process where the transferred charge carries information about its original motion. We have recently suggested that such transfer causes the asymmetry observed in electron transfer induced by circularly polarized light through helical wires. This paper presents the steady-state theory of current transfer within a tight binding model of coupled wires systems. The asymmetry in the system response to a steady current imposed in a particular direction on one of the wires is used to define the efficiency of current transfer. © 2010 American Chemical Society.
