In P-type semiconductor, the doping of Silicon is taken place with:
Correct answer: B. Trivalent
- A. Bivalent
- B. Trivalent
- C. Tetravalent
- D. Pentavalent
Explanation
P-type semiconductors are created by doping silicon with trivalent elements, which have three valence electrons. This creates holes in the crystal lattice that act as positive charge carriers. Bivalent and tetravelent elements do not introduce the necessary charge carriers for P-type doping. Pentavalent elements are used in N-type doping, providing extra electrons rather than holes.

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.
