Such systems, known as concentrated photovoltaics (CPVs) due to their use of concentrating lenses that magnify the solar light before it is converted to energy, have high-efficiency levels but are more costly to manufacture than crystalline silicon or copper-indium-gallium-diselenide (CIGS) cells. Germanium. One of a group of elements that possess properties of both metals and non-metals. SiGe transistors have greater switching speeds and use less power than silicon-based technology. Zone-refined germanium can further be grown into crystals, which are sliced into thin pieces for use in semiconductors and optical lenses. But in infrared light, the opposite is true. It turns out the same phenomenon can happen with dry ice as it sublimates. Like most minor metals, germanium is produced as a by-product of base metal refining and is not mined as a primary material. Trivial name of Germanium is tetrels, crystallogens. sites. It���s hard, grayish-white, and lustrous.

New applications were to come. 100% (1/1) Ge Ge diodes German. Germanium is a shiny silvery metalloid and a semiconductor. The latter makes it an important material in electronics and solar technology. Efforts have been made to grow the commercial market for germanium-based IR systems, such as in high-end cars, but nonmilitary applications still account for only about 12% of demand. One end-use application for SiGe chips is in automotive safety systems. Germanium is chemically similar to tin and silicon and has the same crystal structure as diamond. About half of all such systems, which are heavily dependent upon military demand, include germanium. The development and expansion or fiber optic networks in the 1990s led to increased demand for germanium, which is used to form the glass core of fiber optic cables. Germanium, a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals.
