Abstract

The electrical properties have been studied for GaAs/AlxGa1-xAs based infrared light emitting diode. The characteristics of the device have been analyzed and unusual feature of the device was observed. It operates as avalanche photodiode when it is reverse biased, while it operates as light emitting diode (LED) when it is forward biased..

Keywords

Light emitting diode, Avalanche breakdown, I-V characteristics.
