ZnS/M-12/ZnS structures, with M-12 = Ag, Cu or Cu/Ag, were deposited under vacuum by simple joule heating effect (sublimation or evaporation). The optimum thicknesses of the different layers were experimentally determined: 50/45 nm for ZnS, 11 nm for Ag, 16 nm for Cu and 3 nm/9 nm for Cu/Ag. The presence of the double metal Cu/Ag interlayer induces a significant broadening of the optical transmittance spectrum of these structures. The properties of the structures depend strongly on deposition rate of the different films. When the deposition rates of ZnS, Cu are 0.15 nm/s and 0.30 nm/s for Ag, the averaged transmission, between 400 nm and 1000 nm is 85\% while the sheet resistance is 5.0 +/- 0.2 Omega/sq. These performances allow achieving an averaged factor of merit Phi(M), between 400 nm and 700 nm, of 70 x 10(-3) Omega(-1). This averaged value tends toward those usually achieved by transparent conductive oxides. (C) 2014 Elsevier Ltd. All rights reserved.
