Abstract:A new model for a 1D Si-based light-emitting p-i-n diode (LED) is presented, describing DC electrical characteristics and the internal quantum efficiency (_IQE) as a function of the applied bias, showing good agreement with the simulation results. An optimization scheme, based on the model, shows improved _IQE for engineered heterojunctions by reducing the diffusion current.
