Abstract

We report on the dependency of quantum efficiency of an avalanching silicon n+p light emitting junction on current density and on the injection current from an adjacent lying forward biased an junction. The phenomenon was observed in a three terminal silicon bipolar junction CMOS light emitting device (Si BJ CMOS LED). The total increase in power and quantum coversion efficiency is about three orders of magnitude when compared to earlier published results. The optical emissions are about four orders higher than the low frequency detectivity for silicon CMOS detectors of comparable dimension. Because of its small spot size fabrication capabability (1 micron diameter), high speed capabilty (up to 1 GHz), the devices have numerous potential applications in future CMOS integrated circuitry, hybrid micro-systems and MOEMS.
