Effect of the Electrode Shape on Properties of GaN-Based LED Chips

Abstract:

Before cutting into a single chip, we have tested LED chip with different electrode that is produced under the same condition. With drive current changes, comparing the intensity of light emission of LED chip and operating voltage about the two samples. The conclusion shows that the shape of electrode makes influence on the performance of LED, and the performance of circular electrode with angle is better. The result demonstrates that the better electrode structure of LED chip can improve its performance.
