Abstract:A numerical method was developed to calculate analytical continuation of S-matrix, which describes multichannel scattering at quantum wells, into the region of complex "nonphysical" energy values. One or several resonant hole states related to poles of S-matrix and to the absolute reflection at hole scattering on a quantum well were found to exist in the energy range where only heavy holes may propagate over barriers. Energies of resonant states (i.e. real parts of complex values of S-matrix poles) are close t… Show more
