Abstract

Ferroelectric domain structures have attracted much attention due to their potential applications in storage. In this paper, the molecular dynamics method based on shell model is employed to simulate the uniaxial tensile strain applied to the BaTiO<subscript>3</subscript> thin film, and the effect of strain on the polarization domain structure of BaTiO<subscript>3</subscript> thin film is discussed. The results show that with the increase of strain, the polarization configuration of BaTiO<subscript>3</subscript> film evolves from the initial 180°domain structure to the vortex domain configuration. Moreover, the vortex domain will show certain movement rules with the increase of stress. These results are beneficial to the application research of ferroelectric storage. [ABSTRACT FROM AUTHOR]
