CO Tip Functionalization Inverts Atomic Force Microscopy Contrast via Short-Range Electrostatic Forces

What does a balloon sticking to a wall have in common with an atomic-scale insulator?

When we consider the interaction between atoms, we often think about the forming and breaking of chemical bonds that is best described with quantum mechanics. But electrostatic forces, like the ones responsible for sticking a balloon on a wall after you rub on your head, also play a role at the atomic scale. Salt, made up of sodium and chloride, is a great example of the importance of these forces. The sodium and chloride atoms have different charges that keep the salt crystal together. Nanotechnology is making use of these ionic materials at the atomic scale as an insulating layer – like the plastic coating of a wire. We used an atomic force microscope to investigate one of these materials – Copper with Nitrogen in it – at the atomic scale to see what role electrostatics plays. By picking up or putting down a molecule on the tip, we can change the charge at the end of the tip. We then simulated these two cases – with and without a molecule – using just the electrostatic interaction. The great agreement between our model and our data tell us how important these interactions are even at the scale of two atoms.

Quantifying molecular stiffness and interaction with lateral force microscopy

Alfred J. Weymouth, Thomas Hofmann, Franz J. Giessibl


One of the most impressive atomic force microscopy (AFM) images was taken by Leo Gross and coworkers at IBM of a molecule showing every carbon-carbon bond within it [Gross et al, Science 325, 1110]. A key step was to functionalize the tip with a CO molecule, making the apex of the AFM tip small and chemically inert [Bartels et al, Appl. Phys. Lett., 71, 213]. However, this comes with a complication: The CO isn’t stiff but rather pivots when a horizontal force is applied. Moreover, standard experimental and theoretical approaches have not been able to characterize this torsional spring. We modified our AFM to be sensitive to lateral forces (LFM). As we measure forces along the surface, we are highly sensitive to short-range interactions. We combined both LFM and AFM data of a CO terminated tip probing a CO surface molecule, to determine the parameters of a simple model: two torsional springs interacting via a Morse potential.
