Diode IR, or Infrared Diode, is a type of semiconductor device that emits infrared radiation when forward biased. This technology has found extensive applications in various industries, including consumer electronics, medical devices, industrial automation, and automotive systems. This article aims to provide an in-depth introduction to the diode IR industry, covering its working principle, applications, market trends, and future prospects.

Working Principle of Diode IR

Diode IR operates based on the principle of semiconductor physics. When a diode is forward biased, electrons and holes are injected into the depletion region. As these charge carriers recombine, they release energy in the form of infrared radiation. The wavelength of the emitted radiation depends on the material composition and the doping concentration of the diode. The most commonly used materials for diode IR are gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide phosphide (InGaAsP). These materials have a direct bandgap, which allows for efficient emission of infrared radiation. The emission wavelength can be tuned by varying the composition of the semiconductor material.
