Abstract

A water meniscus formed in air between an atomic force microscope (AFM) tip and a substrate is discussed. A stable meniscus is essential for the validity of the Kelvin equation commonly applied to AFM experiments. Lattice gas Monte Carlo simulations indicate that a stable meniscus has a lower limit in width due to thermal fluctuation. The results show a minimum width of five molecular diameters when the tip becomes atomically sharp.
