Description
By reconstructing exit face wave function using a set of defocused images acquired by Transmission Electron Microscopy, we have measured the projected mean inner potential depth at a grain boundary (GB) in a SrTiO3 bicrystal. As annealing temperature increases, the potential depth at the grain boundary increases, which reveals an exponential profile. For crystalline surfaces, GBs are observed to undergo thermal roughening transition and can be correlated with defaceting transition
