Class 12 Physics Semiconductor Electronics p-n junction diode

p-n junction diode

  • A semiconductor diode is a p-n junction with metallic contacts provided at the ends for the application of an external voltage
  • Thus p-n junction diode is a two terminal device represented as

  • The equilibrium potential barrier can be altered by applying an external voltage V across the diode

There are two methods of biasing a p-n unction – Forward bias and reverse bias
