A review of molecular beam epitaxy of ferroelectric BaTiO3 films on Si, Ge and GaAs substrates and their applications

SrTiO3 epitaxial growth by molecular beam epitaxy (MBE) on silicon has opened up the route to the monolithic integration of various complex oxides on the complementary metal-oxide-semiconductor silicon platform. Among functional oxides, ferroelectric perovskite oxides offer promising perspectives to improve or add functionalities on-chip. We review the growth by MBE of the ferroelectric compoun...

Dislocation-density changes upon poling of polycrystalline BaTiO3

We report evidence for a significant increase of bulk dislocation density upon poling of polycrystalline BaTiO3. The synchrotron high-resolution x-ray-diffraction measurements yield a dislocation density on the order of 10/cm and an associated strain-energy increase of about 20 kJ/m. This implies that the application of an external poling field generates defects in the structure and increases t...
