Discussion on Hamaker Constant

07 May 2024 | Publications

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 between a particle and a substrate. It depends on the material properties of both the interacting...
