Abstract

The effect of different annealing methods on the sheet resistance of indium tin oxide (ITO) on polyimide (PI) substrate has been investigated. As electro-annealing induced the predominant growth of crystallites of ITO thin films along (400) plane, the sheet resistance of ITO films that were electro-annealed for 2 mA at $180^{\circ}C$ considerably decreased from 50 to 28 ${\Omega}/cm^2$.
