Abstract
We summarize a theory of internal coherent tunneling in the
pseudogap region where the applied voltage is below the free
electron gap. We address quasi 1D systems where the gap is
originated by spontaneous lattice distortions (Peierls effect) like
in CDWs or in polyacetylene, as well as generically gapful systems
like conjugated polymers, semiconducting nanotubes and quantum wires
of semiconductors. Their common property is a deep selftrapping of
electrons and their pairs into solitons, polarons, bipolarons. The
instanton approach allows to calculate the interchain tunneling
current both in single electron (polarons) and bi-electron
(bipolarons, solitons pairs) channels.
