Abstract :
In this work, we investigate the influence of the substrate material on the temperature distribution in the active region of the nitride-based quantum well UV light-emitting diodes. Results of mathematical modeling show that the application of the GaN substrate leads to a reduction of the averaged temperature in the active region of a few tens of degrees Kelvin comparing with the sapphire substrate.
