Figure 2: Universal dynamic behaviours observed with different metal nanoclusters.
From: Electrochemical dynamics of nanoscale metallic inclusions in dielectrics
(a–f) In situ TEM images showing the movement of Cu nanoclusters under electric field. Scale bar, 10 nm. (g) TEM image showing the nucleation of Pt nanoclusters. Scale bar, 10 nm. (h) Distribution of the electric field required to drive the dissolution/nucleation processes for different materials. (i–l) In situ TEM images showing the evolution of Ni nanoclusters. Scale bar, 10 nm. (m) Schematic of cluster nucleation from a large embedded metal source. (n) Schematic of the backward growth from the nucleus due to high ion concentration, forming a solid connection with the source.
