Abstract

Electronic properties of InAs_1-xSb_x films with x up to 0.09 have been investigated by reflectance spectra in 1.5-5 eV energy range at room temperature. The real and imaginary parts of the dielectric function were derived by Kramers-Kronig analysis on the reflectance spectra, which show satisfactory agreement with the spectroscopic ellipsometry data. The E 1′ and E 1′ + Δ 1′ peaks are attributed to electronic interband transitions at the E₁ and E₁ + Δ₁ critical points, respectively. The prominent E 2′ peaks, which exhibit high reflectivity and large blueshift, are found to be contributed by hybrid resonance due to the cooperative behavior of both E₂ -state electrons and plasmons.
