Germanium (Ge, atomic number 32) is a lustrous, hard silvery-gray nonmetal in the carbon group, chemically similar to adjacent tin and silicon. A semiconductor like silicon, it’s mainly sourced from sphalerite, with 95% of its infrared optics use for IR lenses/windows. We offer 2  3  4  11  ultra-pure Ge single crystal wafers, ideal for fiber optics, solar cells, LEDs, and nanowire fabrication-meeting strict scientific and industrial needs for reliable semiconductor performance.
