Germanium (Ge) pellets are widely used as an evaporation material in physical vapor deposition (PVD) processes, including thermal and electron-beam evaporation. Germanium thin films are particularly important in semiconductor technology, infrared (IR) optics, and photovoltaic devices due to their excellent optical and electronic properties.
Key Applications:
- Semiconductors: Germanium thin films are used in transistors, diodes, and other semiconductor devices due to its superior electron mobility and compatibility with silicon-based technologies.
- Infrared Optics: Germanium is transparent in the IR spectrum (2-14 µm) and is commonly used in infrared lenses, windows, and filters for thermal imaging and night vision systems.
- Photovoltaics: Germanium serves as a substrate or layer in multi-junction solar cells, improving their efficiency in converting sunlight into electricity.
- Optoelectronics: Used in fiber-optic systems and photodetectors, Germanium films contribute to the effective transmission of signals in optical networks.
