The different program panels. (a) The XRD fitting parameters window, (b) the fit display and (c) the c display. The calculated structure is represented on the right-hand side, drawn using VESTA (Momma & Izumi, 2011BB6). It is composed of an SrTiO3 substrate (N = 2 × 104 unit cells, c = 3.905 Å), an SrRuO3 bottom layer (N = 10 unit cells, c = 3.96 Å), and a superlattice comprising 3 unit cells of PbTiO3 (c = 4.145 Å) and 3 unit cells of SrTiO3 (c = 3.905 Å) repeated ten times.
