Product - Ultra-High-Purity (UHP) Germanium (Ge)

For typical solar and semiconductor applications, 5N Plus Semiconductors recycles and refines germanium to 99.99999% (7 nines or 7N) purity with a bulk resistivity in undoped material on the order of 50 ohm-cm. (The intrinsic resistivity of pure Ge is 46 -cm with an intrinsic carrier concentration of 2.0x1013/cm3.) For specialized detector or research applications, we provide ultra-high-purity (UHP) material up to 1000x more pure (10N). UHP material can be provided in customized formats per customer requirement (e.g. wafers, disks, cylinders, etc.). Contact us to discuss your needs. Our technical team will work with you to provide a solution for your application.
