The large lattice mismatch (8-10%) in the basal plane of YBCO and MgO is accommodated mainly by the formation of a polycrystalline, mosaic structure. The grain boundaries correspond to unique crystallographic interfaces, determined by the crystal symmetry of the substrate and the thin film.}, year = {1990}, journal = {Applied Physics Letters}, volume = {56}, number = {22}, pages = {2243-2245}, issn = {00036951}, doi = {10.1063/1.102932}, note = {cited By 92}, language = {eng}, }
