Abstract

We present high resolution X-ray diffraction data indicating regularly ordered square shaped coherent domains approximately 1200A in length co-existing with longer approximately 9500A correlated regions in a highly strained 5ML SrTiO3 (STO) film grown on Si(001). These long range film structures are due to the Si substrate terraces defined by the surface step morphology. The surface 'step' pattern is comprised of an 'intrinsic' terrace lengh limit due to strain and thermal roughening and an 'extrinsic' inter-step distance due to the surface miscut.
