- Abstract
- To replace thick ITO single layer electrodes, ZnSnO (ZTO)/Ag/indium tin oxide (ITO) multilayer films were investigated as a function of Ag layer thickness. The ZTO/Ag/ITO films showed maximum transmittance in the range of 79.4-89.2%, depending on the Ag layer thickness. The relationship between transmittance and Ag thickness was simulated using the scattering matrix method to understand the high transmittance. As the Ag thickness increases from 6 to 14 nm, the carrier concentration increases from 4.12 x 10(21) to 1.11 x 10(22) cm(-3) and the mobility increases from 8.14 to 17.4 cm(2)/V s. The ZTO (20 nm)/Ag (10 nm)/ITO (30 nm) multilayer films had a sheet resistance of 9 Omega/sq. The ZTO/Ag/ITO multilayer had Haacke's figure of merit of 28.3 x 10(-3) Omega(-1). The ZTO/Ag/ITO films deposited on PET substrates showed dramatically improved mechanical flexibility when subjected to bending test compared to 60 nm-thick ITO single layer electrodes.
