MCQ
In $n-$type of semiconductor, majority carries are:
  • A
    Positron
  • Electron
  • C
    Holes
  • D
    Impure particles

Answer

Correct option: B.
Electron
In $n-$type semiconductor, large number of free electrons is present. Hence, free electrons are the majority charge carriers in the $n-$type semiconductor. The free electrons $($majority charge carriers$)$ carry most of the electric charge or electric current in the $n-$type semiconductor.
