When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
