摘要：

A detailed LEED beam profile analysis of the structural changes induced by the catayltic CO oxidation on Pt(110) has been carried out with a high-resolution instrument (SPALEED). Under conditions where the 1×21×1 phase transition also takes place one observes spatial pattern formation via a faceting process. Facts of roughly uniform size and orientation build up a regular array characterized by a lateral periodicity of 70 lattice units along [110]. The mechanism is discussed in terms of a nonequilibrium structure arising from kinetic instabilities. © 1990 The American Physical Society.
