The ternary mixed crystal system MgxCd1-xTe has recently attracted interest as a basic material for the blue laser diode. We use norm-conserving pseudopotentials in connection with the local-density approximation for ab initio calculations of the stable crystal structure and the lattice constant. Our results are in quantitative agreement with structural properties. The electronic band structure is calculated in dependence on the composition x of the system by the virtual-crystal approximation (VCA). We find a transition from direct to indirect energy gap for x = 0.7 in accordance with experimental data.
