a. Overall atomic structure of a Pt nanoparticle determined in this study, with SiN substrate represented as black and gray disks. b. Identified facet structure of the Pt nanoparticle, showing all facets. c, d. Iso-surfaces of reconstructed 3D density from the electron tomography, before (c) and after (d) the deep-learning based augmentation, respectively. e, f. Tomographic reconstruction volume intensity and traced atom positions. Each slice represents an atomic layer, and the blue dots indicate the traced 3D atomic positions before (e) and after (f) the deep-learning based augmentation. The grayscale backgrounds are iso-surfaces of 3D density.
