Normal versus anomalous roughening in electrodeposited Prussian Blue layers

Electrochemical deposition of Prussian Blue shows a time increase of adsorption rate and produces films with faceted surfaces and smooth morphology at short length scales. Roughness scaling suggests anomalous roughening. However, an interpretation of normal Family–Vicsek scaling provides exponents consistent with roughening dominated by surface diffusion and time-dependent deposition rate characteristic of electrodeposition.

► Surface imaging and roughness scaling of electrodeposited Prussian Blue layers. ► Surface roughness shows typical features of anomalous scaling. ► A novel interpretation of scaling data was proposed resulting in normal exponents.
