摘要：

A one-monolayer thick covalent network of hexagonal boron nitride (h-BN) forms on Pd(1 1 0) upon thermal decomposition of borazine (HBNH)(3). Due to the weak interfacial bonding, the different symmetries of overlayer and substrate, and the lattice mismatch, a variety of rotated domains are created. Several Moire patterns appear in STM images, which can be well explained by simple atomic models. Rings in LEED manifest domain averaging. Non-uniform intensity distributions along these rings measure the abundance of certain domains, depending on particular preparation procedures. The individual Moire domains represent interesting periodic nanostructures that can be imprinted in an adsorbed layer of C-60 molecules. (C) 2005 Elsevier B.V. All rights reserved.
