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) Valence band | (i) Trivalent acceptor atom |
| (b) Conduction band | (ii) Completely empty at absolute zero |
| (c) Energy gap | (iii) Occupied by valence electrons |
| (d) P-type semiconductor | (iv) 4N energy states |
A
a-iii, b-ii, c-iv, d-i
B
a-ii, b-iv, c-i, d-iii
C
a-i, b-iii, c-ii, d-iv
D
a-iv, b-iii, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
The valence band is occupied by valence electrons (4N valence electrons), while the conduction band is completely empty at absolute zero. The energy gap separates these bands, and a p-type semiconductor is formed by trivalent acceptor atoms.
