Depletion layer is found in

Depletion layer is found in Correct Answer diodes

  • Depletion region is formed when two opposite type of semiconductors (p and n) are in contact
  • Due to concentration difference of carriers (electrons in n type and hole in p type), the majority carriers cross the junction and recombine
  • The movement of carriers across the junction creates deficiency of carriers in the semiconductor

  • near the junction; Which is deficiency of electrons in n region (generating positive charge) and deficiency of holes in p region (generating negative charge)

  • The charges on both sides of junction generates electric field which prevents further diffusion of charge carriers
