High resolution images of AB (Roon-soon) lattice

Taken under buffer in tapping mode---individual tiles appear to be resolvable. Strangely, the conditions (we think tip condition) under which individual tiles seem most distinguishable seem to be bad for imaging stripes.

Stripes are well resolved.

In this picture both stripes and individual tiles appear to be well resolved.

Tiles are very well resolved. Stripes less so but they can be made out in the lattice at upper right.

A funny image in which the tip starts out resolving individual tiles, undergoes some change and images the stripes, and undergoes a second change to image tiles well again.

In this image the tiles are very well resolved---until the tip hits what we think is an air bubble on the surface. Afterwards the resolution decreases.
