TL;DR: In this article, the application of IETS to the observation of electronic, rather than vibrational transitions is discussed, and the extension of the method seemed interesting for several reasons, e.g.

TL;DR: In this paper, a tunneling formalism is presented which goes beyond the usual Transfer-Hamiltonian model, and an expression for the conductance is derived in terms of the one particle scatteringt-matrix.
Abstract: A tunneling formalism is presented which goes beyond the usual Transfer-Hamiltonian model. In order to study many body interactions an expression for the conductance is derived in terms of the one particle scatteringt-matrix.

TL;DR: Kronig-Penney-type calculations were used to evaluate the tunneling probability through a thin disordered dielectric film between two metallic electrodes as mentioned in this paper, which indicated that tunneling probabilities increased with increasing disorder.

TL;DR: In this article, the authors investigated tunneling through an oxide barrier into amorphous silicon and found that the tunneling conductance is nearly symmetrical in bias voltage and to increase smoothly from zero bias.
Abstract: Tunneling through an oxide barrier into amorphous silicon was investigated between liquid nitrogen and room temperatures. The tunneling junctions consisted of platinum, silicon oxide, and amorphous silicon in a sandwich configuration. The tunneling conductance, obtained by electronic differentiation, was found to be nearly symmetrical in bias voltage and to increase smoothly from zero bias. The observed temperature dependence of the tunneling conductance is interpreted in terms of localized states within a mobility gap. A mobility gap of approximately 1.6 eV and a density of localized states at the Fermi level of about 1020/eV·cm3 are inferred from the conductance data.
