Germanium has a density of 5.35 g/cc, a melting point of 937°C, and a vapor pressure of 10-4 Torr at 1,167°C. It is classified on the periodic table as a metalloid, which means it possesses properties of metals and non-metals. Like silicon, germanium is a semiconductor and frequently utilized in the fabrication of transistors and integrated circuits.
Stanford Advanced Materials (SAM) is a leading manufacturer and supplier of high purity Germanium Evaporation Materials and a wide variety of evaporation materials. We offer our evaporation materials in powder and granule form. Customized forms are also available upon request.
Germanium is a brittle grayish-white semi-metallic element. It is not found naturally on Earth in its native state due to its high reactivity. However, Germanium can be commercially obtained from zinc ores, certain coals, argyrodite, and germanite. It is used as a semiconductor in transistors, solar cells, and optical related materials.
High purity evaporation materials play a huge role in deposition processes to ensure high quality deposited film. Stanford Advanced Materials (SAM) specializes in producing up to 99.999% purity germanium evaporation materials using quality assurance processes to guarantee product reliability.
• Used in deposition processes including semiconductor deposition, chemical vapor deposition (CVD) and physical vapor deposition (PVD)
• Used for optics including wear protection, decorative coatings, and displays.
Our evaporation materials are carefully handled to prevent damage during storage and transportation and to preserve the quality of our products in their original condition.
