Semiconductor detector — A semiconductor detector is a device that uses a semiconductor (usually silicon or germanium) to detect traversing charged particles or the absorption of photons. In the field of particle physics, these detectors are usually known as silicon… … Wikipedia
Valence band — In solids, the valence band is the highest range of electron energies where electrons are normally present at absolute zero. In semiconductors and insulators, there is a band gap above the valence band, followed by a conduction band above that.… … Wikipedia
valence band — noun The highest range of electron energies in an insulator or semiconductor that can be populated; it corresponds to the valence electrons of the constituent atoms … Wiktionary

Extrinsic semiconductor — An extrinsic semiconductor is a semiconductor that has been doped , that is, into which a doping agent has been introduced, giving it different electrical properties than the intrinsic (pure) semiconductor. Doping involves adding dopant atoms to… … Wikipedia
N-type semiconductor — N type semiconductors are a type of extrinsic semiconductor where the dopant atoms are capable of providing extra conduction electrons to the host material (e.g. phosphorus in silicon). This creates an excess of negative (n type) electron charge… … Wikipedia
