Abstract:

Electrochromic iridium oxide (IrOx) and iridium-tantalum oxide (IrTaOx) thin films were prepared by reactive magnetron sputtering. Composition, density, and structure were determined using Rutherford backscattering spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and electron energy loss spectroscopy. The electronic density of states (DOS) and the solid phase chemical diffusion coefficient (D) were determined for hydrogen in IrOx and IrTaOx by potentiostatic intermittent titration technique (PITT), and electroche

Abstract:

An electrochromic (EC) material is able to change colour under the influence of an electric potential. The development of energy efficient smart windows for architectural applications is at present the subject of intense research for both economic and environmental reasons. Thus there is now a considerable research effort to develop smart windows with natural colour switching properties, i.e. shades of grey. In this regard, a promising metal oxide with a brown-black anodic colouring state is NiO or hydrated nickel oxide (also called nickel hydroxide , Ni(OH)2). The present work outlines the pr

Abstract:

Thin film devices for windows, mirrors, space applications and other purposes, have become an essential part of modern technology. A great advantage with a thin film device is the small amount of material used and the compact volume of the device. Dynamic control of thin film device properties is usually obtained by the application of a potential with a resulting charge transport. To understand this charge transport, thus become of great importance to improve, develop, and invent new thin film devices.

碩士<br>明新科技大學<br>電子工程研究所<br>100<br>Abstract In this study, WO3C thin films were prepared on ITO glass substrates at room temperature by DC magnetron reactive co-sputtering deposition. The various rates of carbon–doped WO3 films were obtained by using different sputtering power for a graphite target. The relationship between microstructures and optical properties of WO3C thin films was investigated. The film thickness was decided by SEM micrographs of the cross-section morphology. The composition of the films was analyzed using an energy-dispersive X-ray spectrometer on a SEM. The rms surface

Before synthesizing multilayer and ternary films, the processing parameters of monolithic V2O5 and WO3 films are optimized by adjusting mainly the oxygen flow. Then, the processing parameters such as the rotating speeding of the substrate, sputtering time, and the substrate temperature are tuning to establish the relations among the processing parameters, t

Comparing with others of inorganic EC materials, it is inexpensive and easy to prepare. There are many physical or chemical methods for preparing EC nickel oxide film. Those methods have their own individual advantages and/or disadvantages. The key point for EC applications is the preparation that would be easy-to-scale-up and low cost.
