Technology of 5 mm Red LED

The technology behind 5 mm red LED involves the process of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in 5 mm red LEDs is typically gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium indium phosphide (AlGaInP). The structure of a 5 mm red LED consists of a p-n junction, where the p-type material has an excess of holes, and the n-type material has an excess of electrons. When an electric current is applied, electrons and holes recombine at the junction, releasing energy in the form of light. The color of the light emitted depends on the energy gap of the semiconductor material.
