RETRACTED: Highly transparent and conductive Sn/F and Al co-doped ZnO thin films prepared by sol–gel method

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of the Editor-in-Chief. Among others, figures 2.(c), 3.(a), (a1), (b), (b1), (c1), 4.(a), (e) and 8. or parts of those figures in this paper have also been presented as belonging to other materials in other publications. This observation is evidence of fraud and therefore it is not certain that the described research and conclusions of this paper belong to the presented images.Among in other papers, these figures show up in:–Properties of fluorine and tin co-doped ZnO thin films deposited by sol-gel method, Journal of Alloys and Compounds, 2013,576, 31–37, DOI: 10.1016/j.jallcom.2013.04.132 as figures 3.(c), 4.(a), (a1), (b), (b1), (c1), 5.(a), (c) and 9.Figures 4.(a), (e) and 8. of this paper can also be found in:–Effect of annealing on the structures and properties of Al and F co-doped ZnO nanostructures, Materials Science in Semiconductor Processing, 2014, 17, 162–167, DOI: 10.1016/j.mssp.2013.09.023 as figures 3.(a), (e), and 6.Figures 3.(a), (a1), (c) and (c1), of this paper can also be found in:–Investigation of structural, optical and electronic properties in Al-Sn co-doped ZnO thin films. Applied Surface Science, 2013, 265, 870–877 as figures 4.(a), (a1), (c), (c1).
