  abstract={We show that the distribution of nanobubbles is inhomogeneous on the (under-water) surface of highly orientated pyrolytic graphite (HOPG), reflecting the atomic steps: The formation of nanobubbles is strongly enhanced at the upper side of the atomic steps, i.e. , the most hydrophobic area on the surface. In contrast, no nanobubbles are formed at the lower side of the steps, i.e. , the most hydrophilic area. The width of this nanobubble-free zone is approximately 20 nm. We thus establish a correlation between surface topography and nanobubble formation. In addition, we show that the profile of nanobubbles is sensitive to the applied AFM tip-force, demonstrating the deformability of nanobubbles.}
