✦ Synopsis

In order to clarify the electronic and optical properties of wide-energy gap zinc-blende structures ZnSe, MgSe and their alloys (ZnSe) 1-x (MgSe) x , a simple pseudo-potential scheme (EPM) within an effective potential, the virtual crystal approximation (VCA) which incorporates compositional disorder as an effective potential, is presented. Various quantities, including the fundamental band gap, the energies of several optical gaps, charge densities, ionicity character, transverse effective charge, and refractive index are obtained for this alloy.

The binary (carbon dioxide + ethane) exhibits an unusual and interesting phase equilibrium behaviour especially in the critical region of the pure components and their mixtures. The critical line of this system was determined by using a flow apparatus. The experimental results were compared with the
