semiconductor· Ge0.542Si0.458
Ge0.542Si0.458 is a germanium-silicon alloy semiconductor with a composition near the 54:46 atomic ratio, belonging to the IV-IV group of elemental semiconductors. This material is engineered to achieve specific bandgap and lattice properties intermediate between pure silicon and germanium, making it relevant for high-performance optoelectronic and photovoltaic applications where tuned carrier transport and light absorption are critical. The composition sits in a region of practical interest for multi-junction solar cells, infrared detectors, and heterojunction devices where lattice matching and bandgap engineering are design priorities.
