The data in this folder correspond to a study of Cu nucleation at F-doped SnO2 electrodes employing high speed lateral molecular force microscopy (HS-LMFM).

The folder contains the following sub-folders:

Figure 1 – Schematic and example of distance dependence of vertically oriented probe oscillation amplitude

Figure 2 – Chronoamperometric transient of Cu deposition and ex-situ atomic force microscopy (AFM) images

Figure 3 – Chronoamperometric transient, in-situ (HS-LMFM) images showing the growth of a single nuclei and ex-situ AFM showing a large portion of the surface after the potential step.

Figure 4 – Snap-shot in-situ HS-LMFM images recorded during the growth and dissolution of Cu a nucleus

Figure 5 – In-situ HS-LMFM images during the growth of a stable nucleus

Supplementary Information:

Supplementary Video 1. Initials stages of Cu nucleation and growth at 58 x 58 nm ITO surface during 49 s, at a constant overpotential of -0.27 V. 

Supplementary Video 2. Growth on a pre-formed stable Cu nucleus on the ITO surface over a period of 57 s at an overpotential of -0.27 V. The final frame shows a superimposed 3D image of the particle growth (as in Figure 5c).
