  2. Intrinsic semiconductor - Wikipedia

    en.wikipedia.org/wiki/Intrinsic_semiconductor

    An intrinsic semiconductor, also called a pure semiconductor, undoped semiconductor or i-type semiconductor, is a semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities.

  3. Semiconductor - Wikipedia

    en.wikipedia.org/wiki/Semiconductor

    Silicon based intrinsic semiconductor becomes extrinsic when impurities such as Boron and Antimony are introduced. The conductivity of semiconductors may easily be modified by introducing impurities into their crystal lattice. The process of adding controlled impurities to a semiconductor is known as doping.

  4. Doping (semiconductor) - Wikipedia

    en.wikipedia.org/wiki/Doping_(semiconductor)

    Doping of a pure silicon array. Silicon based intrinsic semiconductor becomes extrinsic when impurities such as boron and antimony are introduced.. In semiconductor production, doping is the intentional introduction of impurities into an intrinsic (undoped) semiconductor for the purpose of modulating its electrical, optical and structural properties.

  5. Charge carrier density - Wikipedia

    en.wikipedia.org/wiki/Charge_carrier_density

    The mass action law defines a quantity called the intrinsic carrier concentration, which for undoped materials: = = The following table lists a few values of the intrinsic carrier concentration for intrinsic semiconductors, in order of increasing band gap.

  6. List of semiconductor materials - Wikipedia

    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).

  7. PIN diode - Wikipedia

    en.wikipedia.org/wiki/PIN_diode

    The wide intrinsic region makes the PIN diode an inferior rectifier (one typical function of a diode), but it makes it suitable for attenuators, fast switches, photodetectors, and high-voltage power electronics applications. The PIN photodiode was invented by Jun-Ichi Nishizawa and his colleagues in 1950. It is a semiconductor device.

  8. Carrier generation and recombination - Wikipedia

    en.wikipedia.org/wiki/Carrier_generation_and...

    The following image shows change in excess carriers being generated (green:electrons and purple:holes) with increasing light intensity (generation rate /cm 3) at the center of an intrinsic semiconductor bar. Electrons have higher diffusion constant than holes leading to fewer excess electrons at the center as compared to holes.
