    Application
    The Germanium single crystal disc, with its precise (110) orientation and dimensions of 10mm in diameter and 1-3mm in thickness, serves critical applications due to its unique semiconductor properties. This product is essential for the manufacture of high-performance electronic components, such as germanium diodes and transistors, which capitalize on its capability to efficiently rectify and amplify electrical signals. Additionally, its utility extends to infrared optical systems, where germanium's ability to transmit infrared radiation is harnessed in lenses and filters integral to laser and infrared detection technologies. The metalloid's ability to form stable compounds at varying oxidation states further enhances its role in specialized alloys and advanced optical materials, making it invaluable in a range of technological applications where precision and efficiency are paramount.
