Majority CarriersEasyQuestion 20204

Question

Majority carriers in n-type and p-type semiconductors are respectively:
  1. A
    Holes and electrons
  2. B
    Electrons and holes
    Correct
  3. C
    Protons and electrons
  4. D
    Electrons and protons

Correct answer

Electrons and holes

Explanation

n-type: majority = electrons, minority = holes. p-type: majority = holes, minority = electrons. The doping creates an excess of one type; the product n×p = nᵢ² (mass action law) remains constant.
