A CDE Definition
Silicon that is heavily doped with sulfur in order to make it more sensitive to infrared (IR) radiation. Used for IR detectors, black silicon is more efficient at absorbing photons and releasing electrons. It is created by bombarding silicon wafer surfaces with short-pulse femtosecond lasers while exposed to sulfur hexaflouride and other dopants. See silicon.
(Si) The base material used in chips. Pronounced "sil-i-kin," not "sil-i-cone," the latter used to make sealants (see silicone), silicon is the most abundant element in nature next to oxygen. It is found in a natural state in rocks and sand, and its atomic structure makes it an ideal semiconductor material. For chip making, silicon is mined from white quartz rocks and put through a chemical process at high temperatures to purify it. Pure silicon is not electrically conductive. In order to make it conductive, it is chemically combined with other materials such as boron and phosphorus (see doping). See silicon germanium and black silicon.
