چکیده
|
In this paper, a new structure of light-emitting diodes (leds) based on the usage of gallium nitride (gan) semiconductors has been proposed in which, in order to improve the efficiency of the output light, a reflective layer along with two photonic crystal (pc) layers have been employed. the applied changes and their optimization illustrated increase in output light efficiency as much as 133% with respect to a typical led.
