Which of the following dopant is used in silicon to produce p-type semiconductor?

Step-by-step solution

A p-type semiconductor is created by doping silicon with a trivalent impurity from Group 13. These elements possess three valence electrons, one fewer than silicon. When incorporated into the crystal lattice, they create a hole that acts as a positive charge carrier. Gallium (Ga) is a Group 13 element and serves as a trivalent dopant. Antimony (Sb), arsenic (As), and phosphorus (P) belong to Group 15. These are pentavalent impurities that produce n-type semiconductors by donating an extra electron.
