FIG. 4.

IEC for pure structure (black squares), for the case with oxygen vacancy in the MgO layer (red circles), and two cases with 1/8 (blue up triangles) and 1/4 (purple down triangles) oxygen at the interface as a function of MgO thickness. The experimental results for IEC with high (green diamond) and low (orange hexagon) conditions are taken from Ref. 9.
