Cree, Inc. is a global leader in the design and manufacturing of semiconductors and lighting solutions. The company has been at the forefront of the LED industry, providing innovative products that have revolutionized the way we illuminate our world. One of Cree's key contributions to the industry is the development of Cree Infrared LED, which has opened up new possibilities in various applications. Cree Infrared LED is a type of light-emitting diode (LED) that emits infrared light. Unlike visible light, infrared light is not visible to the human eye, but it can be detected by various sensors and devices. This unique characteristic makes Cree Infrared LED a valuable component in numerous applications, ranging from consumer electronics to industrial automation.

How Cree Infrared LED Works

Cree Infrared LED operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. In the case of Cree Infrared LED, the semiconductor material is specifically designed to emit infrared light. This is achieved by using a combination of materials and processes that optimize the energy bandgap of the semiconductor, allowing it to emit light at the desired infrared wavelength. The key components of a Cree Infrared LED include the semiconductor material, a metal contact, and a dielectric layer. The semiconductor material is typically composed of gallium nitride (GaN) or aluminum gallium nitride (AlGaN), which are known for their excellent electrical and optical properties. The metal contact provides a path for the electric current to flow, while the dielectric layer helps to confine the light within the LED.
