NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Acceptor impurity | (i) Creates holes in valence band |
| (b) Pentavalent doping | (ii) Introduces extra electrons |
| (c) Majority carriers | (iii) Formed in n-type semiconductor |
| (d) Thermal excitation | (iv) Increases temperature effects |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
Acceptor impurities, when added to a semiconductor, create holes in the valence band, while pentavalent doping introduces extra electrons, forming n-type semiconductors. Majority carriers are indeed electrons in n-type and holes in p-type semiconductors, and thermal excitation increases the carrier concentration with temperature.
