NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements about semiconductor behavior is correct?
A
In a forward-biased diode, the barrier height decreases, allowing more charge carriers to cross the junction.
B
The depletion layer width increases significantly under forward bias conditions.
C
At absolute zero, the conduction band is partially filled with electrons in semiconductors.
D
Reverse saturation current increases linearly with increasing reverse bias voltage.
Correct Answer
Option A
Detailed Explanation
In a forward-biased diode, the barrier height decreases, which allows more charge carriers to cross the junction, leading to an increase in current as described in Chunk 2. The other statements reflect misconceptions about semiconductor behavior.
