The Surface Morphology and Electrical Properties of Nanostructured CuI Thin Films by Intermittently Sprayed Solution Concentration

Article Preview

Abstract:

The CuI thin films were prepared by a spraying method with acetonitirile as a solvent and CuI as reagents. The parameter investigated in this research is the effect of spraying method either continuously or intermittently sprayed. The influence of spraying method and solution concentration on the surface morphology and electrical properties of CuI thin films were investigated by field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX) and 2 point probe I-V measurement. Nanoparticle CuI was observed for all the thin films prepared. The EDX spectrum confirmed the existence of Cu and I elements. The resistivity of order 10-1 to 100 Ω cm was obtained for the CuI thin film deposited by the spraying technique. The CuI thin films also showed a photoresponse characteristic when measured under illumination condition. These results imply that the prepared CuI thin film deposited by spraying technique exhibit excellent conductivity with nanostructured particles seen.
