摘要：

A monolayer adsorption of Ge on a single-domain Si(001)2x1 surface has been investigated by X-ray excited Auger electron diffraction (AED) and scanning tunneling microscopy. Contrary to the common belief, a significant intermixing of Ge down to at least the fourth layer is identified. This intermixing is found to progress to a stable interface alloy phase that develops fully for annealing at 500-600 degrees C. A possible reason for the alloy phase is discussed to be an elastic interaction from the Si(001) surface. (C) 1997 Elsevier Science B.V.
