Abstract


With the development of modern science and technology , functional research and development of thin film materials gradually become a hot research . In recent decades successfully developed many kinds of functional film materials, including Co / BaTiO 3 nanocomposite films and Fe-Al intermetallic compound film is that these two new functional materials . Co / BaTiO 3 nanocomposite film is a unique composite system , which has a unique optical properties and magnetic properties , and optical materials in electronic devices have a wide range of applications. Fe-Al intermetallic compound film is inertial confinement fusion (ICF) target experimental study with the main target type , but also due to its good oxidation resistance and magneto-optical properties of integrated circuits, magnetic storage material has a good prospect of application . However, the film material on the two of Co / BaTiO 3 nanocomposite film , how to control the particle size distribution of the nanoparticles and the crystal structure of the matrix , produce the desired structure of the film , to maximize the play a ferroelectric thin film and the metal nanoparticle composite function , is currently preparing technical problems encountered . Meanwhile , Fe-Al intermetallic compound film also encountered the same problem , because Fe-Al intermetallic compound film properties for which applications have an important impact , how to prepare high-quality Fe-Al intermetallic compound film is solved important issues. This work for the Co / BaTiO 3 nanocomposite films and Fe-Al intermetallic compound film currently experiencing technical problems , expand their preparation experimental study . Since the pulse laser deposition (PLD) thin film technology unique growth mechanism , so that in the preparation of the film shows its unique advantages. In this experiment , launched by PLD experimental study . For Co / BaTiO 3 nanocomposite thin films we use double block composite target , using hierarchical growth pattern, Co content and the different effects of different periodic structure Co / BaTiO 3 nanocomposite structural properties of the film . Fe-Al intermetallic compound film also uses dual- block composite target by target
