SiGe (/ˈsɪɡiː/ or /ˈsaɪdʒiː/), or silicon–germanium, is an alloy with any molar ratio of silicon and germanium, i.e. with a molecular formula of the form...

Like silicon, germanium naturally reacts and forms complexes with oxygen in nature. Because it seldom appears in high concentration, germanium was found...

detection physics is a device that uses a semiconductor (usually silicon or germanium) to measure the effect of incident charged particles or photons....

Germanium dioxide, also called germanium(IV) oxide, germania, and salt of germanium, is an inorganic compound with the chemical formula GeO2. It is the...

malleable as metals. The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony and tellurium. Five elements are less frequently...
