Semiconductors are manufactured by addition of impurities of

Semicoductors are manufactured by addition of impurities of

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 .

P -type semiconductors are made by adding impurity element

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 .
