The characteristics of light emitted perpendicular to the junction plane (top emission) have been compared with light emitted along the junction plane (side emission) for LED's with active layer carrier concentrations ranging from 1016to ≳ 1019cm-3. Although the top emission always consisted of a single spectral peak, the side emission was often double-peaked. From experimental data and theoretical considerations it was established that double-peaked spectra arise from the absorption and… CONTINUE READING
