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

Options

  1. Aelectrons are stationary
  2. Belectrons neutralize with holes
  3. CO mobility of electrons is extremely small
  4. Datom is electrically neutral

Correct answer

D. atom is electrically neutral

Step-by-step 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.
