0.6 angstrom
That's the resolution of the pictures coming out of Oak Ridge these days using a scanning transmission electron microscope with aberration correction.
Wow. R.L.'s checking out stars no one has ever seen, these folks are imaging atoms. We live in amazing times.
Looking straight down on a silicon crystal, this direct, subangstrom- resolution image shows dumbbell-shaped rows of atoms with a spacing of 0.78 angstrom between each pair. Analysis of the power spectrum shows the presence of information down to a record 0.6 angstrom. The image was obtained with Oak Ridge National Laboratory's aberration- corrected 300-kilovolt Z-contrast scanning transmission electron microscope.
