1. The p-region has a greater concentration of __________ as compared to the n- region in a P-N junction. a) holes b) electrons c) both holes & electrons d) phonons Answer: a Explanation: Holes are the majority charge carriers in p-type material. 2. A p-type semiconductor material is doped with ____________ impurities whereas a n-type semiconductor material is doped with __________ impurities a) acceptor, donor b) acceptor, acceptor c) donor, donor d) donor, acceptor Answer: a Explanation: Donor impurities denote an electron to the n-type material making it a electron majority carrier & vice-versa. 3. In the p & n regions of the p-n junction the _________ & the ___________ are the majority charge carriers respectively. a) holes, holes b) electrons, electrons c) holes, electrons d) electrons, holes Answer: c Explanation: Holes are the majority charge carriers in p-type material & vice-versa. 4. The n-region has a greater concentration of _________ as compared to the p- region in a P-N junction diode. a) holes b) electrons c) both holes & electrons d) phonons Answer: b Explanation: Electrons are the majority charge carriers in n-type material.
