摘要：
We present scanning tunnelling microscopy results of thin dysprosium silicide films grown on Si(001) 2x1. At submonolayer coverages, up to 2000 Angstrom long wires are formed in the (110) direction of the Si(001) surface. Depending on Dy exposure and annealing conditions, both wire assemblies and free-standing wires can be grown. At higher coverages, three-dimensional clusters with rectangular shapes are formed.
