Abstract
The band structure of GeSn and SiSn in zinc-blende structures is predi cted using the empirical pseudopotential. Special emphasis is placed o n the effects of inversions asymmetry such as ionicity. We found that GeSn exhibits a direct band gap whereas SiSn still remains indirect ga p material.
