Q153 / 180 · KCET 2014 · Physics

In n type semiconductor, electrons are majority charge carriers but it does not show any
negative charge. The reason is

  • A
    electrons are stationary
  • B
    electrons neutralize with holes
  • C
    O mobility of electrons is extremely small
  • Correct answer
    D
    atom is electrically neutral

Solution

In n type semiconductor, electrons are majority charge carriers but it does not show any negative charge because atom
is electrically neutral having both electrons and protons making it charge neutral overall.

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