Polarization-dependent x-ray absorption fine structure together with x-ray diffraction have been used to study the local structure in SrTiO3 thin films grown on Si(001). Our data indicate that below a critical thickness of approximately 80 , the in-plane compressive strain imposed on the SrTiO3 layer by the Si substrate results in a tetragonal plus displacive ferroelectric distortion of the SrTiO3 unit cell.
