SEMICONDUCTORS
. A semiconductor is a material which, in terms of its electrical conductivity, lies between metals (conductors) and dielectrics, the conductivity of which depends on the nature of the movement of electrons. Semiconductors include many elements of Groups IV, V, and VI of the Periodic Table of Chemical Elements, such as germanium, silicon, phosphorus, selenium, some minerals, and others. Semiconductors are extremely sensitive to external influences (change of temperature, degree of illumination, radioactive radiation). These semiconductor properties are widely used for various energy transformations, in particular to obtain cold, heat, electrical energy from thermal energy (thermoelectric generator), radiation energy (photovoltaic, solar cell), radioactive radiant energy (nuclear), etc. Generates, amplifies and transforms AC power through semiconductor devices. Almost any modern electronic device relies on the physical properties of semiconductors.
