Research Abstract

Spontaneous formation of superlattice is observed for homoepitaxially grown SrTiO3thin film with Sr-excess composition deposited on Nb-SrTiO3(001) single crystal substrate when the film was deposited using PLD in the magnetic field. It was clarified that this phenomenon is caused by surface-directed spinodal decomposition. This film shows ferroelectricity even at room temperature. This phenomenon would be caused by the internal strain that forms at the interface of layers with different composition.
