Question 30:Why are LEDs made of compound semiconductor and not of elemental
semiconductors?

The correct answer is -LEDs are made up of compound semiconductors and not by the
elemental conductor because the band gap in the elemental conductor has
a value that can detect the light of a wavelength which lies in the infrared
(IR) region.
