The Influence of Hydrogen Gas Treatment on the Characteristics of ZnO Films
نویسندگان
چکیده
This study presents a zinc oxide (ZnO) film deposited on a glass substrate by ultrasonic spraying pyrolysis. The ZnO nanostructure was formed by treating the as-deposited ZnO films with hydrogen. The root-mean-square (RMS) roughness increases from 5.83 nm to 12.53 nm during the treatment for 20 min, but slightly decreases to 11.87 nm at a treatment time of 30 min. In the range 400-500 nm, the transparency of all the films with hydrogen treatment is slightly lower than that of the untreated films. The slight drop in the transparency of the films with hydrogen treatment is caused by scattering from pin-holes or nanostructures on the surface.

We report on transparent ZnO/Ag/ZnO and ZnO/Ag/ZnO/Ag/ZnO thin-films were deposited on the glass substrate by RF and DC sputtering for ZnO and Ag targets, respectively. The electrical and optical properties of the single and double Low Emissivity coatings were investigated with respect to the deposition time of Ag mid layer. The visible transmittance remains about 65% for single and 45% for...
