Figure 3
Temperature dependence of (a) lattice parameter and (b) crystallite size of SrTiO3 extracted from in situ GI-XRD with different temperature ramps of 2, 4 and 8 K min−1 for Sr-rich (EBE) and 4 K min−1 for Sr-depleted layers (RF SP), determined by Rietveld refinement using TOPAS. Dashed lines highlight the relative thermal lattice expansion calculated from the SrTiO3 thermal expansion coefficient (de Ligny & Richet, 1996). Prominent points in the development of the EBE samples' crystallization are highlighted by the letters A, B and C. |
