Abstract

Transparent, smooth and dense zinc tin oxide (ZTO) thin films have been successfully produced by using a new precursor solution, zinc acetate and tin(II) 2-ethylhexanoate mixed with 2-ethanolamine in methoxyethanol. The ZTO films have been prepared by spin-coating, followed by thermal treatment in oxygen atmosphere. The morphology, composition, crystallinity and band gap energy (Eg) of the ZTO thin films have been characterized by Atomic Force Microscopy (AFM), Atomic Emission Spectrometry (AES), X-ray Diffraction (XRD) and UV-vis spectrophotometry. The conductivity of ZTO is about 9.8 × 10−9 S/cm, as estimated from the current-voltage (I-V) curve. The effect of the thermal treatment process on the morphology of ZTO thin films is also discussed.
