- LEDs and LASER diodes are based on semiconductor p-n junctions. - Compound semiconductors, formed from elements in groups III and V (e.g., GaAs, GaP, GaN) or groups II and VI, are commonly used for optoelectronic devices. - The band gap of the semiconductor material determines the wavelength (color) of the emitted light.
