LED light-emitting diode materials and applications，ight-emitting diodes(LEDs) are optoelectronic components made of three-five group compoundsemiconductors, whose core is a PN junction. Under the forward voltage,electrons are injected into the P zone from the N zone, and holes are injectedinto the N zone from the P zone. Some of the minority carriers and the majoritycarriers that enter the opposing area recombine and emit light. The nature ofthe material forming the PN junction (band gap) deter
