Resumen:
The temperature dependence of the Tomlinson/Prandtl model for nanoscale sliding friction is analyzed by considering the properties of the initial and final states between which the tip can move, as well as the energybarrier between them, for various sliding regimes defined by the value of the corrugation factor c. When c4.603, where the friction force increasesmonotonically with increasing sliding velocity up to a critical value equal to the value of F* (lateral force at T = 0) and monotonically decreases with temperature from F* at T = 0. However, completely different behavior is found when 1
