Abstract: Fine-scale field evaporation of stepped (001) and (112) surfaces of tungsten nanotips was studied by field ion microscopy. It was shown that some atoms at kinks and steps are anomalously stable against field evaporation. This effect is responsible for the observed alternate field evaporation near the kink and step sites. The phenomenon of alternate field evaporation could be used to determine an atomic relaxation at kinks on nanotip surface. Using the geometric method of analysis of field ion images, the normal to surface differential displacements of the kink-site atoms were estimated.
