摘要：
The effect of isotropic and anisotropic deformation on electronic and optical properties of semiconducting chromium disilicide CrSi2 is studied by the method of augmented plane waves. The compound is found to be an indirect-gap semiconductor with a band gap width of about 0.3 eV. It is found that the deformation affects the transitions similarly; however, for anisotropic deformation this effect is strongly nonlinear, and the stretching of the lattice up to 106% along the axis a results in the occurrence of a direct transition.
