Match the following for the relevant relations
(
)
| Column I | Column II | ||
| a | n-type semiconductor | q | n_e \gg n_h |
| b | p-type semiconductor | r | n_e \ll n_h |
| c | Intrinsic semiconductor | p | n_e = n_h |
| d | Extrinsic semiconductor | s | n_e \neq n_h |
Options
- Aa-p b-r c-s d-q
- Ba-p b-s c-r d-q
- Ca-q b-r c-s d-p
- Da-q b-r c-p d-s
Correct answer
D. a-q b-r c-p d-s
Step-by-step solution
In type semiconductors, doped with excess electron element(Group 5) so there is excess of electrons and negligible number of holes.
In p type semiconductors, doped with deficient electron element(Group 3) there is excess of holes and negligible number of electrons.
In intrinsic semiconductors there is no doping therefore electron= holes
In extrinsic semiconductors there is doping so either of electron or holes is in excess.
