Between Adhesion and Friction

It has been found that damping to the motion normal to the surface is usually much larger than that in the parallel direction. [Pg.178]

Theoretical analysis indicates that the phononic damping depends strongly on resonance frequency of molecule vibrations. The experimental values of yi )ph in Table 2 are found much larger than the contributions from electronic damping, which is mainly due to the higher resonance frequency of perpendicular vibrations of hydrocarbons on Cu(lOO). [Pg.178]

Adhesion and friction result from the interactions between the surfaces in contact or relative motion. It is therefore ex- [Pg.178]

From the discussions on dynamic adhesion and wearless friction, one may realize that the two events originate from [Pg.178]


The dynamical adhesion process described in this section is also referred to as adhesion hysteresis. We will come back to this subject in later sections when discussing the correlation between adhesion and friction. [Pg.171]

A classification of adhesion according to the changes in the interaction between contiguous bodies in the course of detachment was given by Deryagin on the basis of the analogy between adhesion and friction [7, p. 186]. Friction prevents the tangential displacement of particles, and adhesion prevents the displacement of particles in a direction perpendicular to the surface on which they have been deposited. [Pg.4]

Effects on the Adhesion and Friction between Alkanethiol Monolayers Molecular Dynamics Simulations. [Pg.124]

As described in the last section, the adhesion forces between the particles and the polished surface can provide insight into post-CMP cleaning mechanism and efficiency. As a matter of fact, measurements of adhesion force and alike can directly help in the understanding of CMP and post-CMP cleaning processes. In this section, some basic principles and applications of adhesion and friction force measurements in copper CMP will be presented. The discussion is certainly applicable to post-CMP cleaning processes when similar systems are involved. [Pg.492]

The adhesion and friction forces between silicon oxide surfaces decrease drastically and immediately upon exposure of native silicon oxide surface to vapors of short-chain linear alcohols. The adhesion and friction force changes appear to have reversibility. Re-exposure of the substrate to ambient (humid) air causes the adhesion and friction force to increase back to the original values. The large decrease in friction force in an alcohol environment is in agreement with the decrease in adhesion force. These results indicate the potential of the gas-phase lubrication for MEMS applications. The gas-phase process can be used as an in-use lubrication in which lubricant molecules are supplied to the working... [Pg.1149]

The nano-friction force, measured in torsion mode, is directly proportional to the TMR value (trace minus retrace, in volts), which is given as the difference between the lateral forces scanning left-to-right and right-to-left. Absolute adhesion and friction forces can be obtained with calibration methods but such techniques... [Pg.62]

If static friction is defined as the force needed to establish motion between two surfaces. then experimentally it is not possible to di.stingiii.sh between. stiction. or adhesion, and friction. In some circumstances this may be an appropriate measurement, but it is important to realize that a wide range of values may be obtained, since the result depends on the time available to establish adhesion. [Pg.590]
