Fm. Leibsle et al., STRUCTURE OF THE CU(100)-C(2X2)N SURFACE - A SCANNING-TUNNELING-MICROSCOPY STUDY, Physical review. B, Condensed matter, 47(23), 1993, pp. 15865-15868
Scanning-tunneling-microscopy studies of the Cul {100}-c(2X2)N surface
reveal that it is covered with square-shaped structures with sides 52
+/-4 angstrom long, running parallel to the [100] directions. Within t
hese structures it is possible to resolve a square-based lattice, with
a lattice parameter of 4 angstrom consistent with the c(2X2) structur
e. We use a lattice-parameter-mismatch model based on the bulk-lattice
constants of Cu3N to account for the regularity in shape and size of
the square-shaped structures.
