Abstract

Using the spray pyrolysis technique thin films of indium oxide were prepared on Corning glass (7059) at a substrate temperature of 425° C at different flow rates. The electrical and structural properties of these films were studied. The Hall measurements at room temperature showed that the films prepared in an air flow rate of 7 litre min-1 have the highest mobility of 47 cm2 V-1 s-1 and a minimum resistivity of 1.125 × 10-3 Ωcm. The x-ray diffraction patterns showed that the films have a preferred orientation of [400] which peaks at the air flow rate of 7 litre min-1.
