Si0.94Ge0.06

Si0.94Ge0.06 is a silicon-germanium alloy containing approximately 6 atomic percent germanium in a silicon matrix, belonging to the IV-IV semiconductor alloy family. This material is primarily used in high-speed optoelectronic and integrated circuit applications where the germanium addition provides enhanced carrier mobility and bandgap engineering compared to pure silicon. The controlled Ge composition makes it valuable for heterojunction bipolar transistors (HBTs), strained-layer epitaxial devices, and integrated photonics, where lattice-matched or near-lattice-matched growth on silicon substrates is critical for performance and manufacturability.
