Minisubbands in electron excitation spectra of layered short-coherence-length superconductors

Minisubbands in electron excitation spectra of layered short-coherence-length superconductors Quasiparticle excitation spectra of short-coherence-length layered superconductors ( S ̃ ) are considered as-suming a periodic alternation of the superconducting order parameter Δ ( x ) versus the lateral coordinate x in the c direction. The found self-consistent solution suggests that the electron-hole Andreev scattering in such a periodic Δ ( x ) causes the appearance of minisubbands in the electron spectrum of S ̃ , in a "clean" limit manifested as periodic spikes in the density of electron states at energies E n = ( 2 n + 1 ) Δ 0 ( Δ 0 is the energy gap amplitude; n is a natural number). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review B American Physical Society (APS)

Abstract

Quasiparticle excitation spectra of short-coherence-length layered superconductors ( S ̃ ) are considered as-suming a periodic alternation of the superconducting order parameter Δ ( x ) versus the lateral coordinate x in the c direction. The found self-consistent solution suggests that the electron-hole Andreev scattering in such a periodic Δ ( x ) causes the appearance of minisubbands in the electron spectrum of S ̃ , in a "clean" limit manifested as periodic spikes in the density of electron states at energies E n = ( 2 n + 1 ) Δ 0 ( Δ 0 is the energy gap amplitude; n is a natural number).
