Concept Introduction:
Semiconductors:
Semiconductors are elements that conduct electricity at elevated temperatures because in the semiconductors elements, the electrons can cross the energy gap only at high temperatures. Therefore, conductivity of semiconductors increases with increasing temperatures as many electrons can able to reach the conduction band rapidly at elevated temperatures. Hence the conductivity of the semiconductors lies between that of insulators and good conductors like metals.
Inducing conductivity in semiconductors by the addition of impurities is known as doping.
If the added impurity is capable of providing conduction electrons, then it is known as donor impurity and the semiconductor with such an impurity is known as n-type semiconductor.
If the added impurity is being electron deficient, then it is known as acceptor impurity and the semiconductor with such an impurity is known as p-type semiconductor.
