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) Doping with trivalent elements | (i) Creates excess electrons |
| (b) Doping with pentavalent elements | (ii) Creates holes in the semiconductor |
| (c) Depletion layer formation | (iii) Involves immobile ion-cores |
| (d) Forward biasing of a diode | (iv) Decreases the potential barrier |
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-iv, b-iii, c-ii, d-i
D
a-iii, b-iv, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
Doping with trivalent elements creates holes, while doping with pentavalent elements introduces excess electrons. The depletion layer consists of immobile ion-cores, and forward biasing decreases the potential barrier of the p-n junction.
