Connectivity enhancement of highly porous WO3 nanostructured thin films by in situ growth of K0.33WO3 nanowires

A simple method of enhancing the connectivity between WO3 tree-like structures produced by Electrostatic Spray Deposition (ESD) has been achieved using in situ growth of K0.33WO3 nanowires. The resulting films exhibit a substantially lower electrical resistance without loss of their initial nanostructured morphology.
