1.	What type of semiconductor is obtained when : (i) Ge is doped with in. (ii) SI is doped with P.
Answer» Solution :(i) GE belongs to group 14 and In belongs to group 13. THEREFORE, an electron deficient hole is CREATED and it is a p-type semiconductor. (ii) P belongs to group 15 and Si belongs to group 14. Therefore, an extra electrons gets INTRODUCED and it is a n-type semiconductor.
