We report an analytic expression that accurately represents the dielectric functions ε=ε1+iε2 from 1.5 to 6.0eV of InAsxP1−x alloy films over the entire composition range 0≤x ≤1. We use the parametric model (PM), which describes the dielectric functions of semiconductor materials as a sum of Gaussian-broadened polynomials. The dielectric function spectra are those that we obtained previously by spectroscopic...
We report expressions that allow the dielectric functions ε=ε 1 +iε 2 from 1.5 to 6.0eV of InAs x Sb 1−x alloys over the entire composition range 0≤x≤1 to be calculated analytically. We base our work on the parametric model (PM), which describes the dielectric functions of semiconductor materials as a sum of Gaussian-broadened polynomials. Our reference ε spectra are...
