This project focuses on the effect of annealing temperature to electrical properties of deposited Zinc Oxide (ZnO) thin film. ZnO solutions made from Zinc acetate dehydrate (ZnAC), 2-Methoxyethanol and monoethanolmine (MEA) are deposited onto glass substrates using spin coating technique. Deposited films are annealed at various temperatures from 350degC to(More)
This paper reports on the effect of annealing temperature on the photoluminescence (PL) properties of ZnO thin film. Sol-gel spin coating method was used to prepare the ZnO templates on silicon substrate. ZnO thin films were then deposited by thermal chemical vapor deposition technique by using Zinc Acetate dihydrate as a precursor. Deposited films are(More)
Layer-by-layer ZnO nanoparticles thin films were deposited using sol-gel spin coating technique. Zinc acetate dihydrate, 2-methoxyethanol and monoethanolamine were used in the ZnO solution. Different numbers of film layers were employed to study their effects to the physical, electrical and optical properties of the thin films. XRD patterns showed that the(More)
Nanocomposite thin films consist of conjugated polymer; MEH-PPV and inorganic material; ZnO were deposited using low cost spin coating method. The thin films characteristics were investigated in term of their electrical and optical properties; as each of it were heated at different temperature. The electrical properties of the thin films were studied to(More)
Zinc Oxide (ZnO) thin films were deposited on a glass substrate by sol-gel process dip-coating method. Zinc acetate dehydrate Zn(O<inf>2</inf> CCH<inf>3</inf>)<inf>2</inf>(H<inf>2</inf>O)<inf>2</inf> are used as a starting material while 2-methoxyethanol (C<inf>3</inf>H<inf>8</inf>O<inf>2</inf>) and monoethanolamine (MEA) are used as a solvent and(More)
Zinc Oxide (ZnO) thin films were prepared on glass substrates using sol-gel coating method and the effect of annealing temperatures on the ZnO properties were investigated. The Current-Voltage (I-V) measurement shows electrical properties are improved with annealing temperatures. X-ray diffraction (XRD) spectra indicate annealed samples having preferential(More)
Three different type of materials i.e Au, Pt, and Pd have been investigated as metal contact on Titanium Dioxide (TiO<inf>2</inf>) thin films. These metal contacts have been deposited using sputter coating method. Meanwhile sol-gel spin coating method has been chosen to deposits TiO<inf>2</inf> thin film. The ohmic contact characteristic of the three(More)
This technical paper investigates the electrical properties of the Zinc doped SnO<sub>2</sub> (Zn-doped SnO<sub>2</sub>) nanostructures that have been prepared by the immersion method by different period of immersion process. The experiment was conducted in 3 different time constraint. The thin films were characterized by using current-voltage (I-V)(More)
The electrically conductive zinc oxide (ZnO) nanostructures prepared by sol-gel spin coating are presented. This project has been focused on electrical, optical and structural properties of Al doped ZnO thin film. The effects of Al doping concentration at 0&#x223C;5 at.% on the Al doped ZnO thin film properties have been investigated. This project involves(More)
ZnO thin films were deposited using thermal chemical vapor deposition (TCVD) using gold as the catalyst in a two furnaces system. Carbothermal technique is employed in this work where graphite was mixed into ZnO powder with 1:1 ratio as the precursor. Different thicknesses of gold were deposited on the substrate to study its effect to the properties of the(More)
