摘要
Modulation doped Al0.12Ga0.88N-GaN superlattice structures were used to spread pulse current in nitride-based light emitting diodes (LEDs). Although the 20-mA electroluminescence (EL) intensity of the LEDs with modulation-doped AlGaN-GaN superlattice structures was found to be 10% smaller than that of the conventional LEDs, it was found that LEDs with the AlGaN-GaN superlattice structures could all endure a 2000-V reverse electrostatic discharge (ESD) pulse voltage. Some LEDs can even survive with an 8000-V reverse ESD pulse voltage, which is equivalent to "Class 3B" of Human Body Mode testing.
