The influence of surface irregularities upon the Van der Waals forces between macroscopic bodies

Abstract: SynopsisAn expression is derived for the Van der Waals force between two semi-infinite bodies with small surface irregularities. Calculations are given both for the plane-plane and the plane-sphere configuration. The value of the correction from the surface irregularities upon the Van der Waals force is shown to amount easily to lo-50%.

“…A possible way to cope with this is a perturbative approach: [20][21][22] it is assumed that a rough surface is a small deviation from a smooth surface. Moreover, the slopes of the surface profiles must be small.…”

“…The roughness of the surface has a large effect on the adhesion force, and changing roughness can change the vdW interaction by up to several orders of magnitude [6][7][8][9][10][11][12][13][14]. Several different models have been developed to describe the effects of surface roughness on vdW and electrostatic interactions [4,6,9,13,14]. The model developed by Cooper et al has been experimentally validated for several systems relevant to chemical-mechanical planarization (CMP) and post-CMP cleaning.…”
