These diodes are highly efficient, producing a significant amount of light with minimal power consumption. The key components of a high power infrared LED diode include a semiconductor material, a p-n junction, and a metal contact. The semiconductor material is typically made of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), which allows for the emission of infrared light. The p-n junction is formed by doping the semiconductor material with impurities, creating a region where electrons and holes recombine, releasing energy in the form of light.
