The background of the cover image shows a backscattered‐electron scanning electron micrograph of a heterostructured sample of Sn 12 Sb 2 Te 15 + 2 NiTe 2 . Light green areas correspond to the precipitates of NiTe 2 and the dark green area to the matrix material Sn 12 Sb 2 Te 15 . The two graphs show the Pisarenko plot (Seebeck coefficient vs. charge carrier concentration, bottom left) and the electrical conductivity as a function of temperature (top rightm rotated). Both the charge carrier concentration and the electrical conductivity increase with higher contents x of NiTe 2 . The colors correspond to the values of x = 0 (orange), 0.2 (magenta), 1 (violet) and 2 (blue). More details can be found in the article by Christina Fraunhofer, Stefan Schwarzmüller, James L. Gardiner, G. Jeffrey Snyder, and Oliver Oeckler on page 1345 ff.
