    "abstract": "In this work we present a molecular dynamics simulation of a FFM experiment.\nThe tip-sample interaction is studied by varying the normal force in the tip\nand the temperature of the surface. The friction force, cA, at zero load and\nthe friction coefficient, $\\mu$, were obtained. Our results strongly support\nthe idea that the effective contact area, A, decreases with increasing\ntemperature and the friction coefficient presents a clear signature of the\npremelting process of the surface.",
