Figure 3

(a) Model of the KNN/STO interface, (b) diagram of oxygen octahedral, (c) the in-plane atomic structure of the KNN/STO interface, (d) the density of states of the interfacial atoms, (e) the contour plots of the out-of-plane charge density at the KNN/STO interface and (f) the charge density difference along a slice of the (001) plane for the interface layer. Positive and negative values indicate the accumulation and depletion of electronic charge, respectively.
