英文摘要：
A multi-quantum barrier structure is employed as the electron blocking layer of light-emitting diodes to enhance their perfor- mance. Using the non-isothermal multi-physics-field coupling model, the internal quantum efficiency, internal heat source char- acteristics, spectrum characteristics, and photoelectric conversion efficiency of light-emitting diodes are analyzed systematically. The simulation results show that： introducing multi-quantum barrier electron blocking layer structure significantly increases the internal quantum efficiency and photoelectric conversion efficiency of light-emitting diodes and the intensity of spectrum, and strongly ensures the thermal and light output stability of light-emitting diodes. These results are attributed to the modified energy band diagrams of the electron blocking layer which are responsible for the decreased electron leakage and enhanced carrier con- centration in the active region.
