Abstract
In designing high intensity light emitting diodes (LEDs), substantial increase in efficiency can be achieved with the use of a textured surface, which is characterized by its external quantum efficiency and radiation pattern. The randomness of the inclined facade surfaces contributes substantially to the enhanced efficiency substantially. Such efficiency is strongly dependent upon the textured surface layer's thickness and its distance to the active layer of the diode. To attain the maximum efficiency, an optimal range for these parameters is required. It is found that the radiation pattern of the textured-surface LED has a wider spread of intensity in the angular direction than the flat surface's.
