Discussion on Hamaker Constant
0.0 out of 5 stars
09 May 2008 | Publications | Contributor(s): Stephen Beaudoin, Ravi Jaiswal, Caitlin Kilroy
The Hamaker constant is a force constant used for describing the van der Waals (vdW) force. The magnitude of the Hamaker constant reflects the strength of the vdW force between two particles, or...
Basic Forces in Particle Adhesion
28 Jan 2008 | Online Presentations | Contributor(s): Stephen Beaudoin
Particle adhesion to surfaces is important in a wide range of industrial applications. This brief presentation is designed to provide an introduction to the forces that influence particle...

Roughness models for particle adhesion
20 Dec 2007 | Publications | Contributor(s): Stephen Beaudoin, Ravi Jaiswal, Caitlin Kilroy
The effects of different surface roughness models on a previously developed van der Waals adhesion model were examined. The van der Waals adhesion model represented surface roughness with a...
Particle and Thin Film Adhesion
20 Dec 2007 | Series | Contributor(s): Stephen Beaudoin, Ravi Jaiswal, Caitlin Kilroy
The adhesion of micron and sub-micron scale particles to surfaces is of tremendous interest in a wide range of industrial and civilian applications. We measure directly the adhesion of particles...
Simulation of the Adhesion of Particles to Surfaces
The removal of micrometer and submicrometer particles from
dielectric and metal films represents a challenge in postchemical
mechanical polishing cleaning. Proper modeling of the adhesive
Hamaker Constants in Integrated Circuit Metallization
A new method for determining Hamaker constants was examined
for materials of interest in integrated circuit manufacture. An
ultra-high vacuum atomic force microscope and an atomic force...
A Theoretical and Experimental Study of Surface Forces in Adhesion of Particles to Thin Films
The interactions between micron- and nano-particles and rough surfaces are of great importance and have numerous applications in surface science and biotechnology. It is essential to have...
