An unfamiliar and novel structure observed on a H-terminated Si(100)-(2x1) surface was reported. It was found that the surface density of the structure was proportional to the substrates dopant density. On the basis of STM results and theoretical calculation, the structure was observed to be a dopant-pair structure segregated from the bulk material and incorporated in the top layer of the Si surface.
