摘要
Recently, different and apparently contradicting results were published regarding the influence of crystal defects on the light emission efficiency of silicon LEDs at room temperature [1-6]. In this paper we report our results on light emission of silicon p(+)n diodes with various defect engineering approaches. The p(+) region was formed either by ion implantation or by diffusion; and optionally, additional lattice damage was created by silicon ion implantation. The experiments clearly indicate that lattice defects have a detrimental effect on light emission, contrary to the results published in recent years.
