Paper Abstract

BiFeO3 thin films on different substrates were prepared via Sol-gel method. X-ray diffraction patterns indicated all the films were well-crystallized and gave X-ray peaks corresponding to BiFeO3. The influence of different annealing temperatures and substrates to the Raman spectra was investigated. The Raman spectra of the 750 °C-annealed films gave almost the completed E modes. Compared with the film deposited on Si substrate, the positions of E modes peaks in Raman spectra of the film deposited on LNO-coated Si substrate shifted to higher frequency regions and the existence of the stress between the BiFeO3 films and the substrates was considered to cause the shift.
