【Abstract】 Pt/Ti electrode was prepared by DC magnetron sputtering. Interdiffusion in the Pt/Ti/SiO2/Si interface was examined as a function of various annealing conditions and substrate heating temperatures by using Rutherford backscattering spectrometry, X-ray diffraction and scanning electronic microscopy. It was found that annealing in O2 atmosphere caused the rapid oxidation of Ti layer. The thickness of Ti layer was very important to the interdiffusion of Pt/Ti electrode. The interdiffusion of Pt/Ti caused the poor microstructure and properties of ferroelectric thin films.更多还原
