摘要：

Self-organized nanopattems on vicinal N-adsorbed Cu(001) surfaces have been studied by scanning tunneling microscopy. A stripe pattern appears on the Cu(001)-c(2 x 2)N surface vicinal to the (110) direction. The surface consists of 1-nm-wide lines of clean Cu(001) surface and 2-nm-wide c(2 x 2)N lines. There are two stripe domains, in which the Cu lines are parallel or perpendicular to the step edges. On the surface vicinal to the (100) direction, there appears a one-dimensional array of 5 x 5 nm(2) square patches of c(2 x 2)N surface separated by a 1-nm-wide clean Cu surface.
