Sputter-deposited SrVOx was employed to create transparent conducting SrVOx/Ag/SrVOx films and their optical-electrical properties were examined as functions of SrVOx and Ag thicknesses. With the increase in the thickness of SrVOx films from 15 to 45 nm in the SrVOx/Ag/SrVOx films, the carrier concentration, sheet resistance, and electron mobility were in the range of 2.0 × 1022 − 1.03 × 1022 cm−3, 3.15−2.76 Ω/sq., and 21.99−19.76 cm2/Vs, respectively. The 25 nm-thick SrVOx-based multilayer gave the highest average transmittance (Tav) of 91.5%. The 25 nm-thick SrVOx-based multilayer gave the largest Haacke's figure of merit (FOM) of 144.5 × 10−3 Ω−1. With increasing Ag layer thickness from 9 to 21 nm, the carrier concentration, mobility and sheet resistance of the multilayers were in the range of 1.05 × 1022 − 1.99 × 1022 cm−3, 15.56−22.46 cm2/Vs, and 1.97−6.48 Ω/sq., respectively. The Tav of the SrVOx (25 nm)/Ag/SrVOx (25 nm) multilayer gradually decreased from 95.5 to 82.6% with the Ag layer thickness. The rigorous coupled-wave (RCW) simulations were performed to describe the wavelength-dependent transmittance characteristics of the SrVOx (25 nm)/Ag (15 nm)/SrVOx (25 nm) samples. Based on the phasor examination, the effect of the SrVOx film thickness on the transmittance characteristics of the multilayers is described and discussed.
