Figure 2
Depth dependence of (a) interplanar distance, (b) displacement of the A site and (c) occupancy of (Sr, La) of the LaAlO3/SrTiO3 heterostructure model. Error bars represent the standard deviation of . For most of the plots, the values are smaller than the symbol size. Shaded areas represent regions having occ(A, n) < 0.5. The differences between the resulting structure and are plotted with the origin shifted to the thick horizontal lines. The difference of is magnified by a factor of 10. |
