Abstract
Electroluminescence with power efficiencies larger than 0.1 % is observed from silicon pn diodes prepared by boron implantation. The implanted boron concentration is above the solubility limit for the post-implantation annealing temperature leading to the formation of boron clusters during annealing. The electroluminescence from electron-hole pairs exhibits an anomalous increase in the total intensity with increasing temperature. This behavior is explained by the thermal release of carriers trapped at local potential minima related to the boron clusters.
