- Аннотация: Specific heat of polycrystalline BaTiO3 thin films on the fused quartz substrate was measured by ac-hot probe method. Phase transition temperature and excess entropy were determined as a function of film thicknesses and grain sizes. The variation of the latter was obtained in the limits 30-150 nm by changing of the temperature of the substrate during sputtering while thickness of films 20-1100 nm was controlled by the time of sputtering. It was found that the relation between the thickness and grain size is important for the size effects in polycrystalline films.
