摘要：

Comparison between UHV and air observations on Pd clusters deposited under UHV on a clean graphite surface is made. For the largest cluster (> 10 nm), no dramatic influence of air exposure is observed. Quite surprisingly, we have been able to image in air the surface atomic arrangement of 1.5 nm Pd clusters. They have a tetrahedron shape with (111) facets and are epitaxially oriented: Pd (111)//graphite (00.1), Pd[112BAR]//graphite [01.0].
