A new design of cantilever has been fabricated in order to easily apply the
resonance dynamic measurement technique to lateral interactions between an
atomic force microscope tip and sample. Simultaneous images have been obta
ined in ultrahigh vacuum (UHV) for normal and lateral interactions by activ
ating the cantilever independently at its normal and lateral resonant frequ
ency. The distance dependence of the normal and lateral tip-sample interact
ions have also been investigated. (C) 2000 Elsevier Science B.V. All rights
