    "abstract": "The dynamic characteristics of a tip oscillating in the nc-AFM mode in close\nvicinity to a Cu(100)-surface are investigated by means of phase variation\nexperiments in the constant amplitude mode. The change of the quality factor\nupon approaching the surface deduced from both frequency shift and excitation\nversus phase curves yield to consistent values. The optimum phase is found to\nbe independent of distance. The dependence of the quality factor on distance is\nrelated to \u0027true\u0027 damping, because artefacts related to phase misadjustment can\nbe excluded. The experimental results, as well as on-resonance measurements at\ndifferent bias voltages on an Al(111) surface, are compared to Joule\ndissipation and to a model of dissipation in which long-range forces lead to\nviscoelastic deformations.",
