Impurity semiconductor
WitrynaAdding small amounts of impurities allows control of the conductivity of the semiconductor: shallow donors, such as phosphorous in silicon, produce n -type conductivity (carried by electrons), and shallow acceptors, such as boron in silicon, produce p -type conductivity (carried by holes). Witrynaimpurity , rzeczownik Liczba mnoga: impurities, nieczystość, stan nieczystości [niepoliczalny] According to the Catholic Church, impurity is a sin. (Według kościoła katolickiego, nieczystość jest grzechem.) zanieczyszczenie [policzalny lub niepoliczalny] The water impurity in my hometown is a health risk.

WitrynaA semiconductor is a material which has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass.Its resistivity falls as its temperature rises; metals behave in the opposite way. Its conducting properties may be altered in useful ways by introducing impurities ("doping") into the crystal structure.
