Tunneling in normal-state structures: II

Show Summary Details


This chapter analyses features arising from two-dimensional final states and quantum size-effects tunnelling spectra in normal state structures. Spin-polarized tunnelling is discussed in terms of the Julliere's model, which has been successful in magnetic tunnel junction sensing devices. Assisted tunnelling effects arise from phonons, molecular vibrational excitations, spin waves, and spin-flip and Kondo scattering. Phonon self-energy effects in degenerate semiconductors are discussed with emphasis on Si:B. The Giaever–Zeller resistance peak model is described in connection with experimental data. Inelastic excitation of surface and bulk plasmons is treated. Zero-bias anomalies include the conductance peak provided by Kondo scattering from localized moments in the barrier region. Several many-body theories of tunnelling are reviewed.
