Abstract
The properties of chromium clusters on a thin nanostructured Al2O3 surface
have been investigated by scanning tunneling microscopy (STM) and spectrosc
opy (STS). Oxidation of NiAl(001) leads to the formation of thin ordered Al
2O3 stripes. Upon chromium evaporation small clusters with II mean size of
similar to 3 nm are preferentially formed on top of the oxide stripes. The
STS measurements indicate a metallic behavior of these chromium clusters. (
