Science

Which outcome occurs when energy applied by voltage meets an electron within a reverse-biased semiconductor?

A)Increased depletion region widening
B)Minority carrier tunneling increases sharply
C)Significant thermal vibration increase
D)Majority carrier diffusion decreases sharply

💡 Explanation

Applying a voltage large enough enables tunneling despite the barrier width. Though there are changes to the depletion region voltage causes very shallow increase of minority carrier potential barrier reduction, therefore electrons quantum-tunnel through to neutralize, giving sharp I/V, rather than thermal heating.
