Silicon doped with arsenic is an example of `:`

Silicon doped with gallium forms

Choose the correct options: When silicon is doped with arsenic, n-type/ p-type semiconductor is produced.

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 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 impurity.

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 phosphorous impurity
