Tunneling through ultrasmall NIS junctions in terms of Andreev reflection: a nonlinear response approach
arXiv:cond-mat/9504051 · doi:10.1002/pssb.2221910114
Abstract
The Andreev current through an ultrasmall NIS junction is calculated in a systematic way by means of a nonlinear response approach basing on the elementary Hamiltonian of quasiparticle tunneling. The voltage dependence of current and differential conductance as well as the Andreev conductance are derived for low- and high-impedance environments, respectively.
