Polarization and incidence angle-dependent transmittance of transparent nickel electrodes with various thicknesses

► Light polarization and the incidence angle-dependent transmittance of nickel film on glass. ► Correlation with its thickness, surface morphology and sheet resistance. ► High uniform transmittance over the broad spectral range. ► Facileness in fabrication, ductility, and magnetic functionality for various applications. The polarization and incidence angle-dependent transmittance of thin nickel film with various thicknesses deposited on glass substrates was first investigated by using a modified UV–Vis spectrometer. The thin nickel films showed relatively high uniform transmittance over a wide range of wavelengths, 300–1100 nm. The thickness-dependent dielectric and optical constants extracted from the experimental transmittance are significantly distinct from those of the thick nickel film. In particular, the p-polarized light transmittance largely increases with larger incidence angle, but the s-polarized light transmittance behavior is opposite from that of p-polarized light. The difference of the polarization-dependent transmittance increases parabolically with the incidence angle.
