Cadmium selenide (CdSe) thin films were prepared on indium tin oxide substrate by an alternating cold–hot method, in which cadmium nitrate solution was used as a cold deposition solution, while sodium selenite and potassium borohydride mixed solution was used as a hot deposition solution. The influences of the preparation conditions such as the concentration of Cd(NO3)2, the number of deposition cycle...
Fully transparent tin-doped zinc oxide thin-film transistors (TZO TFTs) were successfully fabricated on glass substrate by radio-frequency sputtering at room temperature. In this reported work, TZO is adopted as the channel layer, SiO2 as the gate insulator and indium tin oxide as gate and source/drain electrodes. The surface morphology and crystallographic structure of the TZO films were evaluated...
In this work are discussed the technology for preparing and characterisation of indium-tin oxide (ITO) and ITO with titanium oxide underlayer thin films with properties appropriate for usage at elevated temperatures as heat reflective coatings and gas sensors. For preparing the samples the methods of radio frequency (RF) and DC-magnetron reactive sputtering were used. Sputtering of indium-tin and...
In this study, the nano-supercapacitors were electrodeposited the gold/manganese oxides thin film with potassium permanganate and gold chloride solution on ITO substrate. It was deposited for 200 s by potentiostatic method (0.7 V v.s. open circuit). The morphology and the microstructure of the films were examined by SEM (scan electron microscopy). The thickness of the thin films was about 30~100 nm...
Passive wireless sensors have been studied by many groups as means of sensing chemical and physical properties in inaccessible locations without the need to include a power source at the sensor location. Indium tin oxide (ITO) thin films are attractive for gas sensing. In this work, we show that laser scribing can be effectively used to fabricate an antenna structure from ITO thin films. This structure...
Zinc Oxide nanocrystals were fabricated in chemical bath deposition process by low temperature 95degC, on glass substrates covered with thin film of ITO. Experiments were repeated for different time of crystal growth. The results were investigated with scanning electron microscope and they show the way of nanostructures growth. Experiment exhibits the speed of nanoflowers growth and explains what...
The electrochemical corrosion behaviors of indium tin oxides (ITO) films were investigated by electrochemical methods in sodium hydroxide solutions. Cyclic voltammetries of ITO films at both anodic and cathodic polarization were carried out. Transmittance spectra, scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis were used for characterization of the optical transmittance, the...
The simultaneous electrodeposition of the Cu-In-Se system was investigated. The study was carried out at pH 1.8 using sodium citrate as complexing agent for the Cu2+ ion. The synthesis of CuInSe2 semiconductor thin film was carried out by electrodeposition on indium-tin oxide (ITO) /soda-lime glass. The simultaneous composition of the Cu, In, and Se was achieved by constant potential electrolysis...
Thin film of zinc oxide (ZnO) was electrodeposited from an aqueous solution of Zn(NO3)2 at 70degC on indium tin oxide (ITO)-covered glass substrate. The analysis of X-ray diffraction(XRD) and scanning electron micrograph (SEM) indicated that the obtained ZnO films had a compact hexagonal wurtzite type structure with preferable (002) growth direction. A sharp near UV emission peak located at 380 nm...
