Abstract
In the reduction of NO with on a Rh(110) surface rectangularly shaped target patterns and spirals with sharp corners have been observed. These patterns can be reproduced with a simple model assuming that the (anisotropic) diffusion is state dependent. Such a dependence is realized in the system Rh(110)/NO + by the presence of different adsorbate-induced reconstructions with varying substrate geometries.
