Picture of Atoms

I thought it was time for an "extreme macro zoom" photo... aka, high-resolution transmission electron microscopy (HRTEM). The distance between each white dot is the inter-atomic distance. The blur on the left is amorphous GaAs, and the region on the right was recrystallized by in-situ annealing. This was in a pile of photos from a materials science research paper I wrote in 1986. I manually developed the film and used "hand dodging" on the print exposure to compensate for lighting imbalances.
