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). 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.

Witryna2 mar 2024 · Characteristics of p-Type Semiconductors: In p-type semiconductors, doping is done with trivalent impurity i.e. impurity from the third group of the periodic table. The impurity in the p-type semiconductor is called the acceptor impurity. Each atom of impurity creates a hole in the crystal. The electrical conductivity is due to the …
WitrynaThe process of adding impurity atoms to the pure semiconductor is called DOPING. Usually, only 1 atom in 10 7 is replaced by a dopant atom in the doped semiconductor.
