NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a semiconductor crystal lattice with Si atoms. Which diagram correctly represents the splitting of 8N energy states into different bands at the atomic level?
A
Two bands separated by a small energy gap, the valence band fully occupied and the conduction band empty at absolute zero.
B
A single continuous band representing overlapping energy states with no energy gap.
C
Two bands with no energy gap, both partially filled with electrons at absolute zero.
D
Three distinct bands with the conduction band partially filled at absolute zero.
Correct Answer
Option A
Detailed Explanation
In Si crystals, the 8N energy states split into two bands, separated by an energy gap, with the valence band fully occupied and the conduction band empty at absolute zero.
