Figure 4

Calculated HAADF-STEM images of the electrode - electrolyte interface for fields of ( a ) zero and ( b ) -2.82 V / Å. Electric double layer formation under the applied field results in a layer of contrast near the gold electrode surface, with the contrast magnitude being related to cesium packing density. Note that averaging multiple simulations would further smooth out contrast features. Poisson noise is included. Scale bar represents 2 Å. Images are simulated through MD-determined structure.
