Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary material used in the fabrication of photodiodes is silicon. Silicon is a semiconductor material that has a direct bandgap. A direct bandgap means that the energy levels of the valence band and the conduction band are aligned. This allows electrons to easily move from the valence band to the conduction band, which results in the generation of an electric current when light is incident on the material.
