The width of depletion region of a junction:

Correct answer: A. Increase with inverse biasing

  • A. Increase with inverse biasing
  • B. Decrease with light doping
  • C. Increase with heavy doping
  • D. None of these

Explanation

The depletion region width on each side of the p-n junction inversely varies with the dopant concentration. Thus, the depletion width decreases when the dopant concentration is higher and increases when the dopant concentration is lower.

About Electronics

A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
