Which one of the following statements is false?

Question

Accepted Answer

1. **Option A (True):** Doping an intrinsic semiconductor like Silicon with a trivalent impurity (Group 13) creates excess holes, forming a p-type semiconductor.
2. **Option B (False):** In an n-type semiconductor, the dopants are pentavalent impurities that provide extra free electrons. Therefore, electrons are the majority charge carriers, and holes are the minority charge carriers.
3. **Option C (True):** As established, in a p-type semiconductor, holes are the majority carriers, making electrons the minority carriers.
4. **Option D (True):** For an intrinsic semiconductor, increasing the temperature provides thermal energy that breaks covalent bonds, creating more electron-hole pairs. This increases the conductivity and consequently decreases the resistance.
