Paper Abstract

This work presents a spectroscopic ellipsometry study of phonon and polariton modes in zincblende group-III-group-V semiconductor layer structures. Contributions to the dielectric function due to infrared-active polar phonon modes and coupled longitudinal-phonon-plasmon modes are differentiated and quantified upon model lineshape analysis. Interface Fano-, Brewster- and surface-guided modes are assigned upon solution of the surface polariton dispersion relation for layered structures, and addressed by experiment. We explain the physical origin of the Berreman-effect.
