To make p type semiconductor pure silicon should be doped with the impurity atoms of

A sample of pure silicon is doped with a trivalent impurity whose each atom creates a hole the concentration holes in pure silicon is 7xx10^(15) holes per cubic metre and density of silicon is 5xx10^(23) a pure silicon sample by a factor of 120 calculate approximately the proportion in which the impurity is added

Silicon doped with arsenic is an example of :

A p-type semiconductor is (i) a silicon crystal doped with arsenic impurity (ii) a silicon crystal doped with aluminium impurity (iii) a germanium crystal doped with boron impurity (iv) a germanium crystal doped with phosphorus impurities.

A semiconductor is doped with a donor impurity

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 .
