Abstract

We report pseudodielectric function data < > = < 1 > + i < 2 > of Zn1−xMg x Se and Zn1−xBexSe samples grown on GaAs substrates. Critical point parameters were obtained by fitting model lineshapes to numerically calculated second energy derivatives of < >, from which the bowing parameters and spin-orbit-splitting ∆1 of the E1 and the E1 + ∆1 gaps were obtained. We discuss the bowing parameters and spin-orbit-splitting ∆1 of the E1 and the E1 + ∆1 gaps.
