Question

Statement I : The conductivity of an intrinsic semiconductor depends on its temperature. \ Statement II: No important electronic devices can be developed using intrinsic semiconductors.

Professor PC Thomas Classes · Answer

(a) : The conductivity of an intrinsic semiconductor depends on its temperature, but at room temperature its conductivity is very low. As such, no important electronic devices can be developed using these semiconductors. Hence, there is a necessity of improving their conductivity. This can be done by making use of impurities.
