A semiconductor is a material that is between the conductor and insulator in ability to conduct electrical current. [1] In many cases their conducting properties may be altered in useful ways by introducing impurities ("doping") into the crystal structure.
A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators.
The study of semiconductors led to the invention of the diode and the transistor, which are indispensable parts of modern electronics systems, computer and telecommunications devices. Another application is for making laser diodes and light-emitting diodes, which are a high-efficiency source of light.
Modern surface-mount electronic components on a printed circuit board, with a large integrated circuit at the top. Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles.
The term solid-state became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology. A semiconductor device works by controlling an electric current consisting of electrons or holes moving within a solid crystalline piece of semiconducting material such as silicon, while the thermionic vacuum tubes it replaced worked by controlling a current of ...
The semiconductor used for carrier generation has usually a band-gap smaller than the photon energy, and the most common choice is pure germanium. [ 25 ] [ 26 ] Most detectors use a p–n junction for carrier extraction, however, detectors based on metal–semiconductor junctions (with germanium as the semiconductor) have been integrated into ...
