The conductivity of intrinsic semiconductors can be increased by adding a suitable impurity . This process is called underline(A) . This can be done with an impurity which is Such impurities introduce underline(B) rich or deficient as compared to the semiconductor. Such impurities introduce underline(C) defects in them. Electron rich impurities result in D type semiconductors while electron deficit impurities result in E type semiconductors .
