Basic Concepts of Diode IR

Diode IR is a semiconductor device that emits infrared radiation when forward biased. It consists of a p-n junction, which is formed by diffusing a p-type semiconductor into an n-type semiconductor. When a forward voltage is applied across the diode, electrons from the n-type region diffuse into the p-type region, creating a depletion region. This depletion region acts as a barrier, preventing electrons from recombining with holes. As electrons move across the junction, they collide with lattice ions, releasing energy in the form of infrared radiation. The intensity of the emitted infrared radiation depends on several factors, including the forward bias voltage, temperature, and the material composition of the diode. Common materials used in diode IR include gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs).
