Explain p - Type semiconductor.

p - Type semiconductor:-

(i) If small amount of trivalent impurity is added with to a pure semiconductor giving a large no. of holes in this, the extrinsic semiconductor therefore formed is termed as p- type semiconductor. This addition of trivalent impurities as gallium and indium give a large no. of holes in the semiconductor crystal. Theses impurities, that produce p- type semiconductors, are termed as acceptor impurities since each atom of them creates one hole that can accept one electron.

(ii) The majority and minority charge carriers are holes and electrons correspondingly.

(iii) The impurity level is here above the valence band.
