    • a parallel plate capacitor model, (formula presented) is proportional to (formula presented), where (formula presented) and a barrier height of 1 eV, we estimate that (formula presented) is (formula presented) since the observed maximum deflection of the top of the cantilever for the data shown is 0.5 nm, and the tip is below this point. Therefore, to a good approximation, we can consider (formula presented) approximately constant

    • Taking the nominal force constant k of a cantilever dipped in a thin film of water on surfaces as (formula presented) for a tip radius of 40 nm, we estimate the force constant in our case to be (formula presented) for an effective tip radius of (formula presented). This radius is determined by the STM tip radius and thickness of the water film. We estimate the former as (formula presented) from STM images, and the latter as (formula presented) from cantilever deflection vs gap distance measurements
