| Abstract | YBa2Cu~O7~thin films have beengrown on vicinal MgO substratesby pulsed-laserablation.The substratetopographyhas beenshownto affect the microstructureof the film. The stepedgesact aspreferentialsites for island nucleation,controlling the in-plane alignmentof the islands.The resultingmicrostructureconsistsof c-axis oriented grainswhich have a large aspectratio. The formationof awell-definedsubstratesurfaceenablesthegrowth of highly orientedYBa2Cu3O7 ~ films, on a substratewhere thereis a largelattice mismatch.The films havebeencharacterizedby both X-ray diffraction techniquesand transmissionelectron microscopy. |
