用动态力谱法测量了真空中石墨（0001）上硅针尖在吸引和排斥状态下的耗散相互作用。能量耗散的速度依赖性检查的振荡振幅的变化。分析表明，能量耗散几乎与针尖-样品速度无关。这表明滞后效应是硅尖与石墨（0001）表面相互作用的主要耗散机制。
The dissipative tip-sample interactions are measured by dynamic force spectroscopy for silicon tips on graphite(0001) in vacuum in the attractive and repulsive regime. The velocity dependence of the energy dissipation is examined by the variation of the oscillation amplitudes. The analysis demonstrates that the energy dissipation is nearly independent of the tip-sample velocity. This indicates that hysteresis effects are the prevailing dissipation mechanisms for silicon tips interacting with the graphite(0001) surface.
