| Abstract: | A formula for the amplitude of electron elastic subbarrier (in the domain of imaginary momenta) scattering by an impurity
modeled as a spherical potential well is derived. An equation is obtained to find the features (poles) of this amplitude in
a complex energy plane in the close vicinity of which the energy spectrum of quantum resonant percolation trajectories in
M-I-M contacts (M = N (normal metal) or S (superconductor) and I is an insulator) with weak (low impurity concentration) structural disorder in the I layer is concentrated 1–4]. |
