Coherent electron tunnelling dynamics in polyacetylene    [PDF]

D. Psiachos

We examine, theoretically, using a mixed classical-quantum electron-lattice dynamics model, electron transport in a polyacetylene wire coupled to electrodes. We identify two qualitatively-different transport regimes: hopping and tunnelling. We discuss the criteria for achieving each one and for minimizing inelastic scattering and decoherence arising from the coupling to the lattice, and we connect our main results to quantities derived from electron dynamics in simpler, three-state model systems. We identify the requirements to have near-ballistic transport.
