Scanning force microscopy (SFM) was used to study the sputter cones re
sulting from the 5 keV Ne+ bombardment of an InP (100) surface. Atomic
force microscopy, force modulation microscopy (FMM) and phase detecti
on microscopy (PDM) images allow to distinguish between sputter cones
and substrate on the basis of topography, local elasticity, adhesion a
nd viscoelastic properties. FMM and PDM clearly indicate that the sput
ter cones' composition is different from that of the substrate. (C) 19
