Abstract : The main goal of this project was to determine the mechanism of operation of an all silicon, electroluminescing device. The device consists of an n+ silicon "wire" supported on top of a layer of porous silicon. Other aims included the evaluation of the device's light emitting efficiency and it's potential as a silicon-based light source. The device emits light over a broad spectrum, extending from the visible into the infrared, with two dominant peaks, at 1.3 and 2.05 microns. An optical quantum efficiency of better than 6% was determined.
