Germanium Sulfide is a crystalline solid used as a semiconductor and in photo optic applications. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Germanium is a Block P, Group 14, Period 4 element. The electronic configuration is [Ar] 3d10 4s2 4p2. In its elemental form germanium's CAS number is 7440-56-4. The germanium atom has a radius of 122.5.pm and it's Van der Waals radius is 200.pm. Germanium is a very important semiconductor. Zone-refining techniques have led to production of crystalline germanium for semiconductor use with extremely high purities. When germanium is doped with arsenic, gallium, or other elements, it is used as a transistor element in thousands of electronic applications.

American Elements semi conducting materials are crystal structures produced from ultra high purity starting materials synthesized by our high purity production facility which includes several large electric muffle furnaces, a tube furnace for hydrogen reduction, 50 gallon glass-lined Pfaudler reactors supported by our analytical laboratory containing X-ray diffraction, SEM, AA, BET surface area, and ICP Spectrometry for trace metals analysis. See a discussion of American Elements Ultra High Purity and Analytical capabilities. See Crystal Growth for processes used to fabricate semiconductor materials, which include:

  • Crystal "pulling" by the Czochaiski method for production of semiconductor materials
  • Flux growth and gradient freeze
  • Directional solidification of fluorites using both the Bridgman-Stockbarger and float zoning techniques
