What type of semiconductor is generated by adding small amounts of gallium to silicon?
A) n-type semiconductor
B) Ga-type semiconductor
C) p-type semiconductor
D) insulating semiconductor

Question

Quizplus · Accepted Answer

Adding small amounts of gallium to silicon creates a p-type semiconductor. This is because gallium has one less valence electron than silicon, which creates a hole in the lattice structure when incorporated into the crystal. This hole acts as a positive charge carrier, creating a p-type material.
