Tailoring WO_3 thin layers using spray pyrolysis technique

摘要

The deposition technique is responsible for the morphological and crystalline properties of the thin films obtained by spray pyrolysis. The influence of the deposition parameters on the WO_3 films properties is presented. The main characterisationrnconcerns the topography (AFM), crystalline parameters rn(XRD), surface tensions (contact angle) and opto-electronic properties. Due to the changes on the deposition parameter, dense and porous WO3 films were obtained with radically different interface properties.
