Also, in HRTEM images, you can see the columns of atoms in a lattice.
Now that the new generation of spherical-aberration-corrected TEMs are coming out you can get images that look like "ball and stick" models of your lattice.
A group down the hall from us uses Aberration-Corrected Z-STEM on CdSe quantum dots.
Here is a link to their latest paper in Nano Letters (ASAP) if you have access:
I attached an image in case you don't. See attachements.
