Single‐asperity Friction in Friction Force microscopy: The composite‐tip model
Applied Physics Letters, 1995Co-Authors: Constant A.j. Putman, Masaru Igarashi, Reizo KanekoAbstract:Friction measurements on muscovite mica and glass have been performed with a Friction Force microscope using Si3N4 tips. The environment was changed from ambient conditions to N2‐ or Ar‐gas conditions. In ambient conditions, the Friction‐versus‐load curves showed a nonlinear behavior closely following the Hertzian contact mechanics of a single‐asperity contact: Friction Force ∼load2/3. For the same tip under gaseous conditions the Friction Force increased linearly with the load, indicating multi‐asperity contact. A new model is proposed to explain this change in the nature of the Friction behavior. In this composite‐tip model, the tip is formed by the actual Si3N4 tip and ‘‘solidlike’’ contaminants present in enclosed cavities between tip and sample surface.

radiation Friction Force effects on electron dynamics in ultra intensity laser pulse
Physics of Plasmas, 2019Co-Authors: Yanzeng Zhang, S I KrasheninnikovAbstract:The electron dynamics in the ultra-high intensity laser pulse with radiation Friction Force in the Landau-Lifshitz form are studied. It is demonstrated that widely used approximation, where only the term dominating the dissipation of electron kinetic energy is retained in the expression for the radiation Friction, is incorrect for the case of diverging electron trajectories. As a matter of fact, for large Friction Force effects, all components of the radiation Friction Force in the Landau-Lifshitz form have the same order in the equation of motion for electron trajectories, being equally important for both electron trajectory and thus energy gain in the case of diverging electron trajectories (e.g., determined by the superposition of few electromagnetic waves).

radiation Friction Force effects on electron dynamics in ultra intensity laser pulse
arXiv: Plasma Physics, 2018Co-Authors: Yanzeng Zhang, S I KrasheninnikovAbstract:The electron dynamics in the ultra-high intensity laser pulse with radiation Friction Force in theLandau-Lifshitz form are studied. It is demonstrated that widely used approximation, where onlythe term dominating the dissipation of electron kinetic energy is retained in the expression for theradiation Friction, is incorrect for the case of diverging electron trajectories. As a matter of fact, forlarge Friction Force effects, all components of the radiation Friction Force in the Landau-Lifshitz formhave the same order in the equation of electron motion, being equally important for both electrontrajectory and thus energy gain in the case of diverging electron trajectories (e.g. determined bythe superposition of few electromagnetic waves).
