A semiconductor of `Ge` can be made `p`-type by adding

A P-type semiconductor

p-type semiconductor is

p-type semiconductor can be obtained by adding - ____ to pure germanium.

n-type semiconductor can be obtained by adding - ____ to pure germanium .

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 .
