Semiconductors can be compounds such as gallium arsenide or pure elements, such as germanium or silicon. Physics explains the theories, properties and mathematical approach governing semiconductors. Examples of Semiconductors: Gallium arsenide, germanium, and silicon are some of the most commonly used semiconductors.
semiconductor, any of a class of crystalline solids intermediate in electrical conductivity between a conductor and an insulator. Semiconductors are employed in the manufacture of various kinds of electronic devices, including diodes, transistors, and integrated circuits.
In simple words, Semiconductor devices are a type of electronic components that designed, developed and manufactured based on the Semiconductor materials like Silicon (Si), Germanium (Ge) and Gallium Arsenide (GaAs).
A semiconductor is called a semiconductor because it is a type of material that has an electrical resistance which is between the resistance typical of metals and the resistance typical of insulators, so it kind of, or "semi"-conducts electricity.
A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.
Semiconductors works due to imbalance of electrons that carry negative charge. This imbalance of electrons generates positive (where there are excess protons) and negative charges (where there are excess electrons) at two ends of surfaces of the semiconductor material. This is how semiconductor works.
In addition to consumer electronics, semiconductors play a central role in the operation of bank ATMs, trains, the internet, communications and other parts of social infrastructure, such as the medical network used for the care of elderly, among other things.
At the heart of all charge-coupled devices (CCDs) is a light-sensitive metal oxide semiconductor (MOS) capacitor, which has three components consisting of a metal electrode (or gate), an insulating film of silicon dioxide, and a silicon substrate.
transistor, semiconductor device for amplifying, controlling, and generating electrical signals.
A silicon atom has 14 electrons around the nucleus, and of these, there are 4 valence electrons on the outermost orbital. When this is made into a single crystal, it can be used as a material for semiconductor products. When it crystalizes, the nuclei share electrons and they bond with 8 electrons around each nucleus.
