Abstract
Due to the large variety of properties offered by the binaries of telluride family CdTe, ZnTe, MgTe, HgTe and MnTe as well as their mixed ternary alloys, these materials have been extensively studied but, some points bearing on several properties have never previously reported or are still not clear. In this paper, we report results on the conduction and valence band offsets of the pseudomorphically strained Cd1-xXxTe layer on relaxed Cd1-yXyTe substrate, X = Zn, Hg, Mg and Mn. Based on the Van Der Walle model, calculations have been performed for the all range of material and substrate 0 <= x, y <= 1. For the CdMnTe diluted magnetic semiconductor which we focus more interest du to its considerable current interest for applications, calculations have been done without and with correction taking into account magnetic effect of magnesium ions Mn++. As it is found that the introduction of only a few percent of Mn into CdTe provides a unique opportunity to combine two important fields in physics, semiconductivity and magnetism. We can take advantage both of possibility of applications in solid-state lasers and exceptional magnetic properties offered by this magnetic diluted semiconductor. This study presents important quantities that are required to model quantum structures and offers a fast and inexpensive way to check device designs and processes.
