SrTiO3/Si Polarization and Interface Structure

Combining TEM, synchrotron XRD, and first principles theory, we have determined the SrTiO3/Si interface structure and the properties of ultrathin (2 nm) SrTiO3 films. The chemical bonding at the interface leads to a polarization throughout the SrTiO3, but both theory and experiment find that there is no ferroelectric transition.
