Toward single-particle tomography of excited nanomaterials Top: Side-view image of a quantum dot with a defect excited by a laser (green) rolled to present a different orientation. STM: Conventional STM image of a quantum dot before (right) and after a roll (left). SMA: Slice through the electronic density of the excited quantum dot before and after the same roll. DFT (density functional theory): 3-D quantum calculation of a quantum dot defect projected into slices at two orientations for comparison with experiment.
