Electron and positron energy distributions in Cd0.5Mn0.5Te alloy

We calculated the electron and positron band structure for Cd0.5Mn0.5Te all oy and presented electron and positron charge densities as a function of po sition in the unit cell. The densities of states both electronic and positr onic at different points of reciprocal space were performed. In these calcu lations, we used the empirical pseudopotential method and the virtual cryst al approximation coupled with the independent particle model. (C) 1999 Else vier Science S.A.
