Abstract
(110) and (103) YBa2Cu3O7 films have been grown onto exact and vicinal (110) SrTiO3 substrates, and on vicinal (110) MgO substrates with a SrTiO3 buffer layer. The samples are carefully characterised by reciprocal space mapping with x-ray diffraction, in order to investigate the features of the typical double domain of (110) and (103) YBa2Cu3O7 structure. It is demonstrated that vicinal cut substrates allow to select one film/substrate epitaxial relation. The growth properties of these thin films deposited on vicinal surfaces are discussed.File in questo prodotto:
