Sketch of the geometry during in situ TEM experiments (not to scale). The neck area between two particles is characterized by its diameter .
Bright-field images and SAD patterns of Ni agglomerate before (a) and after annealing (b) for 1 min at −10 V. The STM tip is visible in the upper right corners (enhanced online). [URL: http://dx.doi.org/10.1063/1.3452327.1]10.1063/1.3452327.1
Ex situ high angle annular dark-field image of the agglomerate after rapid consolidation. The sintered agglomerate was identified by its shape, size, and location on the indexed specimen grid. The SAD pattern was taken with a TEM from the marked area.
Current and voltage vs time for (a) −3 V annealing, (b) first annealing at −10 V, and (c) final annealing at −10 V during which rapid consolidation occurred. The arrows mark temporary increases in local resistance due to neck formation.
