| Research Abstract |
In this research, we aim low-temperature fabrication of metal oxide crystal films for substitution of tin-doped indium oxide by a new film processing technique which can achieve low environmental load, high deposition rate, and cost effectiveness. ZnO films with visible-light transparency over 70 percents and electrical resistivity about 5X10-3 ohm cm were successfully fabricated by spin-spray method with controlling the flow rate of solution and rotation rate of table. When water-soluble polymer was used as an additive, the crystal shape was changed by different manner with trisodium citrate. The performance of ZnO films prepared by using water-soluble polymer was not improved compared with those prepared with trisodium citrate. The results indicated that the adsorbed organics and film structure strongly affected electrical properties.
