Abstract

Graphical abstract: Highlights: We studied the structural, optical and surface properties of oxide/metal/oxide films. The influence of the heat treatment on the physical properties was analyzed. The electrical conductivity of different oxide/metal/oxide films was measured and compared. Abstract: In this paper the influence of the heat treatment on the structural and optical properties of oxide single-layer and multilayer transparent thin film structures of ITO/Au/ITO, AZO/Au/AZO, TiO2 /Au/TiO2 and Bi2 O3 /Au/Bi2 O3 type is studied. The single-layer oxides and respective multilayer structures have been deposited on glass substrates by successive DC magnetron sputtering using metallic targets In:Sn, Zn:Al, Ti and Bi, in reactive (for the oxide films) or inert (for the metallic Au interlayer films) atmosphere. Good quality transparent conducting thin film structures have been obtained, with resistivity ∼10 −4 Ω cm and transmittance ∼75%. The wetting surface properties in function of time exposure at UV radiation (254 nm) have been also studied before and after heat treatment performed at 450 °C.
