Ge0.3Si0.7

Ge0.3Si0.7 is a germanium-silicon alloy semiconductor with a 30% germanium and 70% silicon composition, belonging to the SiGe alloy family widely studied for advanced electronic and photonic applications. This material is primarily used in high-speed integrated circuits, heterojunction bipolar transistors (HBTs), and infrared detectors, where its bandgap and lattice properties offer advantages over pure silicon in terms of carrier mobility and optical response. The alloy is notable for enabling improved performance in rf/microwave devices and thermal imaging systems compared to conventional silicon, making it particularly valuable in applications requiring either speed or wavelength-specific sensitivity.
