SiGe has been used in high-efficiency solar cells and the channel of metal-oxide semiconductors due to its narrow band gap and high mobility. However, few reports on the atomic-level structure and properties of the SiGe alloy by theoretical calculations have been published, and therefore there are few theoretical considerations on the SiGe alloy. In this study, we searched for stable atomic configurations of the SiGe alloy using first-principles calculations and genetic algorithm, and analyzed the band structure of the stable atomic configurations.
