... and because of the heteroepitaxial growth of films WO 3 in which the parameters of plane ITO (440) are slightly larger than the ones of WO 3 planes. The relation between shifts of XRD peaks ... decrease of the magnitude of peak (200) and a raise of peak (001). Moreover, peak (020) is shown obviously in the case of 250 nm. When the ITO layer have a thickness about 30...
