NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) n-type | (i) Doping with trivalent atoms |
| (b) p-type | (ii) Doping with pentavalent atoms |
| (c) Majority carriers (n-type) | (iii) Holes |
| (d) Majority carriers (p-type) | (iv) Electrons |
A
a-ii, b-i, c-iv, d-iii
B
a-i, b-ii, c-iii, d-iv
C
a-ii, b-ii, c-iv, d-iii
D
a-ii, b-i, c-iii, d-iv
Correct Answer
Option A
Detailed Explanation
In n-type semiconductors, doping with pentavalent atoms (like phosphorus) introduces extra electrons, making electrons the majority carriers. In p-type semiconductors, doping with trivalent atoms (like boron) creates holes, which are the majority carriers.
