- Abstract
- The crystallization of amorphous BaxSr1-xTiO3 (BST) thin films was studied in a synchrotron x-ray scattering experiment. In a 550 Angstrom thick film, the crystallization to perovskite phase was occurred at around 700 degrees C, while a 5500 Angstrom thick film became crystalline at 500 degrees C. The thickness dependence of the crystallization was attributed to the observed intermediate phase nucleated near 600 degrees C at the interface. In thin films, high annealing temperature was required due to the energy barrier between the perovskite phase and the intermediate phase. In tie thick film, the perovskite phase was nucleated directly from the amorphous phase in the bulk of the film concurrent to the nucleation of the intermediate phase at the interface.
