Growth dynamics of epitaxial (Ba,Sr)TiO3 thin films deposited at different temperatures on SrRuO3/SrTiO3 substrates by pulsed laser deposition is investigated by transmission electron microscopy. The films exhibit a layered structure comprising sublayers with distinctive features in regard to the remaining strain, density of mislit dislocations and/or lattice defects, and growth habit. We correlate these temperature-dependent features with the predominant mislit-strain relaxation mechanisms for each one of the detected growth regimes. The thickness dependence of the film structure is discussed within the framework of the predictions for a kinetically modilied Stranski-Krastanov growth mode. |
