| 中文摘要 | Morphology and superconductivity of YBa2Cu3-(7-delta) thin films grown on vicinal SrTiO3 substrates by pulsed laser deposition are studied. Ex situ atomic force microscopy and scanning tunneling microscopy are used to observe the film surface morphology, Novel anisotropic step-mediated island growth is found for the first time. The anisotropic evolution of the surface morphology is discussed in terms of the anisotropic surface diffusion. Relatively low deposition temperature (750 degreesC is found to be the optimum condition for ultra-smooth step-mediated growth of YBa2Cu3O7-delta thin films. Tilting of the substrates is found favorable for the superconductivity of YBa2Cu3O7-delta thin films grown an them, The critical temperature at zero resistance (T-c0) of YBCO films is found to be a function of the vicinal angle of the SrTiO3 substrates.
