The elemental semiconductors are those composed of single species of atoms, such as silicon (Si), germanium (Ge), and tin (Sn) in column IV and selenium (Se) and tellurium (Te) in column VI of the periodic table. There are, however, numerous compound semiconductors, which are composed of two or more elements.
Which type of elements are semiconductors?
Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide.
What are the seven semiconductor elements?
Types of semiconductor materials
- Group IV elemental semiconductors, (C, Si, Ge, Sn)
- Group IV compound semiconductors.
- Group VI elemental semiconductors, (S, Se, Te)
- III–V semiconductors: Crystallizing with high degree of stoichiometry, most can be obtained as both n-type and p-type.
