Abstract

A novel low-temperature (LT) surface-science facility based on a two-chamber UHV system has been developed for combined investigations of the electronic and geometric structure of surfaces, employing scanning tunneling microscopy atT≤ 5 K and high-resolution (Δ E ≌ 10 meV) photoemission atT≤ 50 K. A LHe-cooled sample manipulator enables cold transfer of samples (and tips) between the two chambers. Here we present the LT-UHV facility together with first measurements on silver surfaces and silver clusters prepared in nanopits of a graphite surface.
