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).

A fourth element is often added to a I-III-VI 2 material to tune the bandgap for maximum solar cell efficiency. A representative example is copper indium gallium selenide (CuIn x Ga (1–x) Se 2, E g = 1.7–1.0 eV for x = 0–1 [1]), which is used in copper indium gallium selenide solar cells.
The table below shows some of the parameters of common superconductors.X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla.

Organic semiconductors are solids whose building blocks are pi-bonded molecules or polymers made up by carbon and hydrogen atoms and – at times – heteroatoms such as nitrogen, sulfur and oxygen. They exist in the form of molecular crystals or amorphous thin films .
II-VI semiconductor compounds are produced with epitaxy methods, like most semiconductor compounds. [2] The substrate plays an important role for all fabrication methods. Best growth results are obtained by substrates made from the same compound ( homoepitaxy ), but substrates of other semiconductors are often used to reduce the fabrication ...
