The concentration of the dopant used affects many electrical properties. Most important is the material's charge carrier concentration. In an intrinsic semiconductor under thermal equilibrium, the concentrations of electrons and holes are equivalent. That is, In a non-intrinsic semiconductor under thermal equilibrium, the relation becomes (for low doping): where n0 is the concentration of conducting electrons, p0 is the conducting hole concentration, … 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).
