Abstract

We described the hysteretic behavior of AC driven infrared, red, white, and blue light-emitting diodes. It was found that hysteresis in the AC driven LEDs increases with higher driving frequencies and in LEDs with higher band gaps. The hysteresis was attributed to the non-instantaneous response of the system to the changing applied voltage.
