    A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).

    Commercially significant is zinc selenide, which is used in some infrared optics. Cadmium selenide is a pigment but its use has been declining because of environmental considerations. Copper indium selenide ( CuInSe 2 ) has attractive potential for photovoltaic devices, but these applications have not been implemented widely. [ 1 ]

    en.wikipedia.org/wiki/2000s_commodities_boom

    The price of zinc rose sharply in early 2007 after a five-year secular bear market, then collapsed to nearly their original starting price by the end of the next year. [102] Zinc also exhibited similar bullish trading patterns as most metals did since 2004, but with a different overall price. [105] Zinc sale prices were 80 cents per pound in ...

    en.wikipedia.org/wiki/Zinc_compounds

    Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...
