AbstractOptical constants of HgxCd1-xTe alloys are modeled for the first time over the spectral range from 1.5 eV to 6.0 eV for all compositions 0 ≤ x ≤ 1. The employed model is the modified Adachi's model, which utilizes variable line broadening instead of the conventional Lorentzian one. The model takes into account transitions at critical points E0, E0+Δ0, E1, E1+Δ1, E0', E2(X), and E2(Σ), as well as excitonic effects at lowest four critical points. Model parameters are determined using a global optimization routine, namely acceptance-probability-controlled simulated annealing algorithm. Excellent agreement with the experimental data is obtained in the entire investigated energy and composition ranges.
