  2. Silicon - Wikipedia

    en.wikipedia.org/wiki/Silicon

    Silicon. face-centered diamond-cubic (cF8) Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium ...

  3. Silicone - Wikipedia

    en.wikipedia.org/wiki/Silicone

    Silicone is a widely used material in the aerospace industry due to its sealing properties, stability across an extreme temperature range, durability, sound dampening and anti-vibration qualities, and naturally flame retardant properties. Maintaining extreme functionality is paramount for passenger safety in the aerospace industry, so each ...

  4. Silicon dioxide - Wikipedia

    en.wikipedia.org/wiki/Silicon_dioxide

    Silicon oxide layers could protect silicon surfaces during diffusion processes, and could be used for diffusion masking. [ 47 ] [ 48 ] Surface passivation is the process by which a semiconductor surface is rendered inert, and does not change semiconductor properties as a result of interaction with air or other materials in contact with the ...

  5. Monocrystalline silicon - Wikipedia

    en.wikipedia.org/wiki/Monocrystalline_silicon

    A silicon ingot. Monocrystalline silicon, more often called single-crystal silicon, in short mono c-Si or mono-Si, is the base material for silicon -based discrete components and integrated circuits used in virtually all modern electronic equipment. Mono-Si also serves as a photovoltaic, light-absorbing material in the manufacture of solar cells.

  6. Silicone rubber - Wikipedia

    en.wikipedia.org/wiki/Silicone_rubber

    Silicone rubber. An uncured piece of liquid silicone rubber. Silicone rubber is an elastomer (rubber-like material) composed of silicone —itself a polymer —containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations. Silicone rubbers are often one- or two ...

  7. Polycrystalline silicon - Wikipedia

    en.wikipedia.org/wiki/Polycrystalline_silicon

    Polycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry. Polysilicon is produced from metallurgical grade silicon by a chemical purification process, called the Siemens process.

  8. Isotopes of silicon - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_silicon

    Silicon-34 is a radioactive isotope with a half-life of 2.8 seconds. [1] In addition to the usual N = 20 closed shell, the nucleus also shows a strong Z = 14 shell closure, making it behave like a doubly magic spherical nucleus, except that it is also located two protons above an island of inversion . [ 14 ]

  9. Crystalline silicon - Wikipedia

    en.wikipedia.org/wiki/Crystalline_silicon

    Crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells. These cells are assembled into solar panels as part of a photovoltaic system to generate solar power from sunlight. In electronics, crystalline silicon is typically the monocrystalline form of silicon, and is used for ...
