Germanium (Ge)
Germanium is a rare, silvercolored semiconductor metal valued for its excellent electronic and optical properties. It has long been used in the manufacture of rectifiers, transistors, infrared optical systems, and highefficiency photovoltaic solar cells.
Highpurity germanium is essential for producing HPGe radiation detectors, which are widely used in nuclear physics research, environmental monitoring, homeland security, and medical imaging due to their exceptional energy resolution.
In advanced semiconductor fabrication, highpurity germanium also serves as a source material for molecular beam epitaxy (MBE). Its precise purity and controlled deposition characteristics make it indispensable for both semiconductor research and commercial device production.
