Schematic diagram of the band alignment for the (CdSe) 7 /(ZnTe) 7 SL and electronic wave functions. Schematic diagram of the band alignment for the (CdSe)7/(ZnTe)7 SL (a) and electronic wave functions of the upper valence miniband and the lower conduction miniband in three interfaces cases: (b) non-symmetric case, (c) ZnSe interfaces, and (d) CdTe interfaces. Envelope functions are plotted along the [001] axis (molecular average between the charge densities on cation and anion sites) for clarity reasons and to better evidence the location of electronic states in the structure.
