Q154 / 180 · COMEDK 2015 · Physics

In a semiconductor diode, the reverse biased current is due to drift of the free electrons and holes caused by

  • A
    thermal expansion only
  • B
    impurity atoms only
  • Correct answer
    C
    Both (a) and (b)
  • D
    Neither (a) nor (b)

Solution

In a semiconductor diode, the reverse biased current is due to drift of the free electrons and holes which are produced by thermal expansion, impurity atoms etc.

Hence, the correct answer is option: 'C'.
