摘要
Atmospheric pressure metal organic chemical vapor deposition (AP-MOCVD) was used to prepare iron doped titanium dioxide thin films. Thin films, between 40 and 150 nm thick, were deposited on Si, SiO2 and Al2O3 substrates using titanium tetra isopropoxide and ferrocene as metal organic precursors. TiO2 iron doping was achieved in the range of 1-4 at.%. The film morphology and thickness, polycrystalline texture and doping content were studied using respectively scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), The influence of growth temperature, deposition time, substrate type and dopant partial pressure were studied. Electrical characterizations of the films were also performed. (C) 1999 Elsevier Science S.A. All rights reserved.
