Germanium is useful for monochromators for beamlines used in single crystal neutron scattering and synchrotron X-ray diffraction. The reflectivity has advantages over silicon in neutron and high energy X-ray applications. [90] Crystals of high purity germanium are used in detectors for gamma spectroscopy and the search for dark matter. [91]
A crystal detector includes a crystal, usually a thin wire or metal probe that contacts the crystal, and the stand or enclosure that holds those components in place. The most common crystal used is a small piece of galena ; pyrite was also often used, as it was a more easily adjusted and stable mineral, and quite sufficient for urban signal ...
Bismuth germanium oxide or bismuth germanate is an inorganic chemical compound of bismuth, germanium and oxygen. Most commonly the term refers to the compound with chemical formula Bi 4 Ge 3 O 12 ( BGO ), with the cubic evlitine crystal structure , used as a scintillator .
Gallium and germanium are used in semiconductors, while germanium is also used in infrared technology, fibre optic cables and solar cells. Antimony is used in bullets and other weaponry, while ...
Germanium monoselenide is a chemical compound with the formula GeSe. It exists as black crystalline powder having orthorhombic (distorted NaCl -type) crystal symmetry; at temperatures ~650 °C, it transforms into the cubic NaCl structure. [ 3 ]
