High Purity Ge Germanium Evaporation Material Germanium Pellet Granule for Evaporative Coating CAS NO.7440-56-4

High Refractive Index: Germanium has a high refractive index (around 4.0 at 10 µm), making it ideal for IR optics and imaging systems.

Broad Infrared Transparency: Germanium is transparent in the infrared spectrum, making it suitable for IR optical coatings, lenses, and filters.

Excellent Electron Mobility: Germanium’s electron mobility is higher than silicon, enhancing its application in semiconductor devices.

High Purity: Germanium used in evaporation is highly purified (typically ≥ 99.99%), ensuring uniform and high-quality thin films.

Low Melting Point: Germanium has a relatively low melting point (937°C), making it easy to evaporate in standard PVD systems.

Compatible with Silicon: Germanium is often used in conjunction with silicon in semiconductor and optoelectronic applications.

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.

Application

1. 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.

2. 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.

3. Photovoltaics: Germanium serves as a substrate or layer in multi-junction solar cells, improving their efficiency in converting sunlight into electricity.

4. Optoelectronics: Used in fiber-optic systems and photodetectors, Germanium films contribute to the effective transmission of signals in optical networks.
