The Total solution for NCERT class 6-12
Classify each of thefollowing as being either a p-type or an n-type semiconductor:
(i) Ge doped with In (ii) Bdoped with Si.
(i) Ge (a group 14 element) is doped with In(a group 13 element). Therefore, a hole will be created and the semiconductorgenerated will be a p-type semiconductor.
(ii) B (a group 13 element) is doped with Si (agroup 14 element). Thus, a hole will be created and the semiconductor generatedwill be a p-type semiconductor.
