REFLECTANCE OF NONLOCAL CONDUCTING SUPERLATTICES

We calculate the p-polarized reflectance spectra of a semi-infinite superlattice made up of alternating spatially dispersive conducting layers, accounting exactly within a hydrodynamic model, for the propagation of plasma waves. Besides the expected structure originated from the infinite-superlattic...

Sumario:We calculate the p-polarized reflectance spectra of a semi-infinite superlattice made up of alternating spatially dispersive conducting layers, accounting exactly within a hydrodynamic model, for the propagation of plasma waves. Besides the expected structure originated from the infinite-superlattice bulk-plasma resonances, we find an extra series of peaks which arise from the semi-infinite-superlattice surface resonances. The latter originate from standing plasma waves at the surface layer, whose resonant frequencies are larger than those in the interior layers due to confinement effects.
