Pn Bias Behaviour

Question 1

Forward bias effects

Answer 1

Depletion width decreases, diffusion current increases, drift current remains da same

Band gap between n and p region decreases and diode behaves like a conductor

Question 2

Reverse bias effect

Answer 2

Depletion region width increases, diffusion current drop to roughly 0, drift current remains the same

Band gap between n and p region increases and diode beavers like an insulator
