WebAbstract—This work presents a comprehensive analysis of the SiGe band structure using a Tight-Binding based approach within the virtual crystal approximation. We analyze the material properties of bulk relaxed SiGe and biaxially compressed strained systems. The simulation approach has been benchmarked against experimental data wherever possible.
WebWe have 100mm, 150mm and 200mm Silicon Germanium (SiGe) wafers. SiGe strained silicon provides an alternative substrate for CMOS manufacturing using silicon. SiGe wafers are suitable for mixed-signal circuits.SiGe is much less expensive than Gallium Arsenide (GaAs) heterojunction technologies. WebThe band structure of SiGe has been calculated using the coherent-potential approximation in conjunction with a realistic but local pseudopotential model. The effects of alloy disorder manifest themselves in complex band energies, each with an imaginary part inversely …
WebSolar cell is generally constructed using crystalline silicon (c-Si) which has absolutely low absorption coefficient because of its indirect band structure; therefore, it is less preferable for solar technology. Here alloy of SiGe is considered due to its low energy band gap and increase in absorption coefficient as compared to Si.
