Influence of Al, In codoping in enhancing the Figure of Merit of ZnOthin films for TCO Applications
Published online by Cambridge University Press: 19 January 2016
Abstract
AIZO (Al and In codoped ZnO) thin films were deposited on soda lime glasssubstrates by the ultrasonic spray pyrolysis (USP) technique. The sprayingsolution was prepared from zinc acetate dihydrate, aluminum acetyl acetonate andindium acetate. Depositions were carried out at three different temperatures,425, 450 and 475 °C. Structural, morphological, optical and electricalproperties were examined with respected to the deposition temperatures. All AIZOfilms grown with (002) preferential orientation confirmed from X-ray diffractionanalysis. Hexagonal nanostructures were observed from Scanning electronmicroscopy (SEM) analysis. Minimum electrical resistivity of 2.52x10-3 Ω-cm was achieved for AIZO films.
