R. Bennewitz et al., Aspects of dynamic force microscopy on NaCl/Cu(111): Resolution, tip-sample interactions and cantilever oscillation characteristics, SURF INT AN, 27(5-6), 1999, pp. 462-466
Ultrathin films of NaCl on Cu(111) have been studied using a dynamic force
microscope. We present images with atomic resolution at step sites on the N
aCl films, Force spectroscopy measurements of the tip-sample interaction on
NaCl-covered areas and the Cu substrate are analysed with respect to elect
rostatic, van der Waals and short-range contributions, The interaction cont
rast between NaCl and Cu is shown to be reflected in the oscillation charac
teristics of the cantilever, First results of a resonance analysis with the
help of a novel digital oscillation control system are presented. Copyrigh
