| Abstract: | A new approach of preparation of ferroelectrics LiNbO 3 thin film is described The pseudospark electron beams with nanosecond duration can be used for film deposition through the interaction of beam and target to cause rapid melting, vaporization and explosion of target materials, and nucleation and crystallization of ablated target cluster with similar ratio of components occur on the surface of substrates Physical processes of the ablation and deposition of this new technology have been investigated The observation of high resolution electron microscopy, X ray diffraction, photo electronic energy spectroscopy have been presented Some experimental results of the preparation of Ferroelectrics LiNbO 3 thin film are presented in this paper Experimental results show that such a new approach of film deposition with wide application possesses some unique advantages |
