Abstract:
We report a detailed temperature dependent study of polarized piezoreflectance (PzR) for two AlInP 2 epilayers that exhibit different degree of ordering in the range between 23 and 500 K. The polarized PzR measurements showed anisotropic character along the [110] and [110] directions for the partially ordered sample. The PzR spectra were fitted using the first-derivative of a Lorentzian line shape functional form. The direct band-, crystal field splitting- and spin-orbit splitting to conduction band transition energies which are denoted as E g , E g +Δ E 12 and E g +Δ E 13 respectively, at various temperatures were accurately determined. The temperature dependence of these near direct band-edge critical points transition energies were analyzed by the Varshni expression and an expression containing the Bose-Einstein occupation factor for phonons. The parameters that describe the temperature variation of transition energies were evaluated and discussed.
