扫描隧道显微镜研究表明，Cu{100}-c(2×2)N表面覆盖有正方形结构，其边长为52±4A，平行于晶向。在这些结构中，可以分辨出正方形的晶格，其晶格参数为4A，与c(2×2)结构一致。我们用基于Cu3N体晶格常数的晶格参数失配模型来解释正方形结构的形状和尺寸的规律性
Scanning-tunneling-microscopy studies of the Cu{100}-c(2×2)N surface reveal that it is covered with square-shaped structures with sides 52±4 A long, running parallel to the directions. Within these structures it is possible to resolve a square-based lattice, with a lattice parameter of 4 A consistent with the c(2×2) structure. We use a lattice-parameter-mismatch model based on the bulk-lattice constants of Cu 3 N to account for the regularity in shape and size of the square-shaped structures
