Comparative studies of Al-doped ZnO and Ga-doped ZnO transparent conducting oxide thin films
We have investigated the influences of aluminum and gallium dopants (0 to 2.0 mol%) on zinc oxide (ZnO) thin films regarding crystallization and electrical and optical properties for application in transparent conducting oxide devices. Al- and Ga-doped ZnO thin films were deposited on glass substrates (corning 1737) by sol-gel spin-coating process. As a starting material, AlCl3⋅6H2O, Ga(NO3)2, ...
متن کاملSpin-coated Ga-doped ZnO transparent conducting thin films for organic light-emitting diodes
Gallium doped zinc oxide (GZO) thin films have been prepared by a simple sol–gel spin coating technique. XRD results showed the preferential c-axis orientation of the crystallites and the presence of the wurtzite phase of ZnO. A lowest resistivity of 3.3 × 10−3 cm was obtained for the ZnO film doped with 2 at% of Ga after post-annealing at 500 ◦C for 45 min in a H2 atmosphere. All the films sho...
متن کاملGrowth and optical properties of ZnO nanorod arrays on Al-doped ZnO transparent conductive film
ZnO nanorod arrays (NRAs) on transparent conductive oxide (TCO) films have been grown by a solution-free, catalyst-free, vapor-phase synthesis method at 600°C. TCO films, Al-doped ZnO films, were deposited on quartz substrates by magnetron sputtering. In order to study the effect of the growth duration on the morphological and optical properties of NRAs, the growth duration was changed from 3 t...
متن کاملElectronic structure of conducting Al-doped ZnO films as a function of Al doping concentration
Transparent conducting Al-doped ZnO films were deposited by atomic layer deposition with various of Al doping concentrations. In order to explain the change in resistivity of Al-doped ZnO films depending on Al doping concentration, we investigated the correlations between the conducting property and electronic structure in terms of atomic configuration, the evolution of the conduction band and ...
متن کاملTransparent conductive Nd-doped ZnO thin films
Transparent Nd-doped ZnO films with thickness in the range of 70 to 250 nm were grown by pulsed-laser deposition (PLD) on c-cut sapphire substrates at various oxygen pressures and substrate temperatures. A wide range of optical and electrical properties of the films were obtained and correlated to the composition and crystalline structure. The Nd-doped ZnO films are smooth, dense, and display t...
