Electrons present in P-type material due to thermal pair generation are:
Correct answer: B. Minority carriers
- A. Majority carriers
- B. Minority carriers
- C. Dual carriers
- D. None of these
Explanation
Electrons are minority charge carriers in p type semiconductors. In an intrinsic semiconductor, some of the electrons in the valence band gain enough energy (thermal energy) to move to the conduction band. So there are a few electrons in the conduction band, and these electrons leave holes in the valence band as they go to the conduction band.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
