Electrochromism in nickel oxide and tungsten oxide thin films: Ion intercalation from different electrolytes

Structural and mechanical properties of nanostructured tungsten oxide thin films

This study presents structural and mechanical properties of WO3 thin films deposited on glass substrates at different temperatures by radio frequency reactive magnetron sputtering. WO3 films deposited at temperatures up to 200uC are found as amorphous, but crystalline at 300 and 400uC. Chemical analysis reveals the overstoichiometry of the films. The diffusion of sodium ions from glass substrat...

Transparent p-type epitaxial thin films of nickel oxide.

Transparent p-type nickel oxide (NiO) thin films have been epitaxially grown on (0001) Al2O3 substrates by a chemical solution method of polymer-assisted deposition for the first time. The films have a high optical transparency of above 95% in the wavelength range of 350-900 nm.

Ellipsometrically determined optical properties of nickel-containing tungsten oxide thin films: Nanostructure inferred from effective medium theory

Transparent Conductive Oxide Thin Films

Transparent conductive oxides (TCO) have high optical transmission at visible wavelengths and electrical conductivity close to that of metals. They also reflect near infrared and infrared (i.e., heat) wavelengths, and are used in products ranging from energy efficient low-e windows to photovoltaics. One of their most important uses is for transparent electrical contacts. Virtually all applicati...

Polaron and Phonon Properties in Proton Intercalated Amorphous Tungsten Oxide Thin Films

We report on the evolution of the polaron and phonon mode properties in amorphous tungsten oxide thin films measured by spectroscopic ellipsometry in the infrared to ultraviolet spectral regions as a function of the intercalated proton density. A parametric physical model dielectric function is presented, which excellently describes the ellipsometry data over a large intercalated charge-density...
