The conductivity of a semiconductor material can be varied under an external electrical field. 31.1 Introduction . Ever since the first transistor was invented way back in 1948, the semiconductor industry has been growing at a tremendous pace. An extrinsic semiconductor is one in which an impurity with a valency higher or lower than the valency of the pure semi conductoris added, so as to increase the electrical conductivity of the semiconductor.
