Abstract:

A detailed ab initio analysis is carried out for the cationic substitution doped mixed alloy's theoretical EXAFS simulations. Suitable data processing codes are used for the subsequent experimental EXAFS spectral fittings. We have simulated various x-ray scattering single and multiple paths around the core atomic environ and subsequently they are compared with the spectroscopic results. As-obtained parametric values are used to find the hardening and crystalline disorders among these heavily Be doped ZnSe ternaries. The hardening phenomenon amongst the alloys are explained by using the doping related variations of the Zn-Se and Be-Se bond lengths and the presence of structural stabilities during the initial stages of alloying.
