Classify each of the following as being either a p-type or an n-type semiconductor:
(i) Ge doped with In
(ii) B doped with Si.
(i) Ge belongs to group 14 and In belongs to group 13, In has 3 valence electrons while Ge has 4 valence electron. On replacement an electron deficient hole was created, therefore it is a p-type semi- conductor.
(ii) B belongs to group 13 with 3 valence electrons and Si belongs to group 14 with 4 valence electrons. Therefore on replacement there will be a free electron and it is n-type semiconductor.
