Classify each of the following as being either a p-type or n-typesemiconductor : (i)Ge doped with in (ii) B doped with Si.

Classify each of the following as being either a p-type or n-typesemic

1.	Classify each of the following as being either a p-type or n-typesemiconductor : (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 is carrated 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
