The formation of ADBs was attributed to different crystal symmetry of the film and the substrate. The analysis showed that upon annealing the density of ADBs decreased and the dielectric properties improved.}, year = {2002}, journal = {Applied Physics Letters}, volume = {81}, number = {23}, pages = {4398-4400}, issn = {00036951}, doi = {10.1063/1.1523632}, note = {cited By 14}, language = {eng}, }
