Abstract
A study was conducted on the fundamental issues concerning capillary forces and meniscus structure by considering a spherical AFM tip in three dimensions interacting with a planar substrate. For this prototypical geometry, the effect of humidity and molecule-tip interaction strength on capillary force was studied systematically. This paper proposes a mean-field DFT approach as a computationally effective method for calculating the pull-off force.
