Light-emitting diodes (LEDs) are devices designed to efficiently convert electrical energy into electromagnetic radiation, most of which is visible to the human eye. Some of the disciplines involved in the understanding and utilization of LEDs are reviewed, with emphasis on the III-V semiconducting compounds and GaP LEDs in particular. Salient features

Light Emitting Diodes (LEDs) convert electrical power to generally visible optical power and are simply p-n-junction devices, when biased in the forward direction. They produce light through spontaneous emission whose wavelength is determined by the bandgap of the semiconductor in which the carrier recombination takes place.

Light-emitting diodes are simple compact optical sources which have certain attractions for use in digital optical transmission systems. They are easy to fabricate and therefore potentially cheap, can be modulated at high data rates, and emit moderate output powers which can be coupled reasonably efficiently into optical fibres.

In this chapter, the basics of the light emitting diodes are reviewed. Since its invention in the 20th century, the light emitting diode has evolved into a major life-changer for human being. Most of the focuses have been on the family of GaN-based materials in the past two decades.

1970 International Electron Devices Meeting, 1970
There is a growing interest in the development of devices that can efficiently convert electrical energy into light, particularly visible light. Of special interest is the possibility that such devices may be electrically and, hopefully, even physically compatible with existing electrical devices, particularly integrated circuits.
