1.	Classify each of the following as being either a p-type or n-type semiconductor: (i) Ge doped with In (ii) B doped with Si.
Answer» Solution :(i)Ge is Group 14 element and In is Group 13 element. Hence, an electron deficit HOLE CREATED and therefore, it is p-type. (ii) B is Group 13 element and Si is Group 14 element, there will be a free electron. Hence, it is n-type
