  2. Silicon - Wikipedia

    en.wikipedia.org/wiki/Silicon

    Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure element in the Earth's crust. It is widely distributed throughout space in cosmic dusts , planetoids , and planets as various forms of silicon dioxide (silica) or silicates .

  3. Silicon compounds - Wikipedia

    en.wikipedia.org/wiki/Silicon_compounds

    Naturally occurring silicon is found in silicate and aluminosilicate minerals. One of the most common silicon compounds found in the Earth's crust is silicon dioxide or silica, which often occurs as quartz. Organosilicon compounds are fairly stable due to the similarity in strength of the Si–C bond to the C–C bond.

  4. Silicon dioxide - Wikipedia

    en.wikipedia.org/wiki/Silicon_dioxide

    Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula SiO 2, commonly found in nature as quartz. [5] [6] In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and abundant families of materials, existing as a compound of several minerals and as a synthetic product.

    en.wikipedia.org/wiki/List_of_semiconductor...

    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).

    Scientists have used silicon to make the chips that power classical computers for decades. But natural silicon comes with small impurities that can cause qubits to lose information and make any ...

  8. Silicate mineral - Wikipedia

    en.wikipedia.org/wiki/Silicate_mineral

    In mineralogy, silica (silicon dioxide, SiO 2) is usually considered a silicate mineral rather than an oxide mineral. Silica is found in nature as the mineral quartz , and its polymorphs . On Earth, a wide variety of silicate minerals occur in an even wider range of combinations as a result of the processes that have been forming and re-working ...
