The constituent particles of a solid have
The conductivity of a superconductor is
The conductivity of intrinsic semiconductors can be increased by adding a suitable impurity. This process is called $(P)$. This can be done with an impurity which is $(Q)$ rich or deficient as compared to the semiconductor. Such impurities introduce $(R)$ defects in them. Electron rich impurities result in $(S)$ type semiconductors while electron deficit impurities result in $(T)$ type semiconductors.
