Abstract

Utilizing the sol–gel method, Al-Ti codoped ZnO (ATZO) NANOSTRUCTUREd THIN FILMS were synthesized. The X-ray diffraction (XRD) analysis, field emission scanning electron microscopy (FE-SEM) and atomic force microscopy (AFM) methods were used to investigate the structure, morphology and surface roughness of the THIN FILMS. From XRD patterns, it was found that reducing atmosphere causes an improvement in the crystallinity of the ATZO thin film. The post annealing process in the reducing atmosphere of 95 % N2-5% H2 has revealed that cause a significant reduction of the RESISTIVITY from 13´106 Wcm to.006´106 Wcm, along with an increase in transmittance from 86.39% to 88.41%. It was observed that the grain size varies from 23 nm to 29 nm and RMS roughness of the THIN FILMS were found to be around 8 nm. According to their optical transparency and RESISTIVITY values, ATZO NANOSTRUCTUREd THIN FILMS can be used in thin film transistors (TFTs).
