This work provides a novel approach for enhanced radiative transitions in silicon microelectronics devices. A process based on hot carrier injection is monitored for the creation of a low dimensions defect layer near the emitter-base interface of bipolar transistors. New energy levels are induced together with a potential barrier. Carrier confinement is correlated with the potential barrier height. The increase of light emission is related to high injection effects in the junction. Results present an advance toward Si-based optoelectronic devices.
