The background of the cover image shows a backscattered‐electron scanning electron micrograph of a heterostructured sample of Sn₁₂Sb₂Te₁₅ + 2 NiTe₂. Light green areas correspond to the precipitates of NiTe₂ and the dark green area to the matrix material Sn₁₂Sb₂Te₁₅. 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 NiTe₂. 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.

封面图像的背景显示了Sn ₁₂ Sb ₂ Te ₁₅ + 2 NiTe ₂异质结构样品的反向散射电子扫描电子显微照片。浅绿色区域对应于NiTe ₂的析出物，深绿色区域对应于基体材料Sn ₁₂ Sb ₂ Te ₁₅。这两张图显示了Pisarenko图（塞贝克系数与电荷载流子浓度的关系，左下图）和电导率随温度的变化（右上角旋转）。NiTe _2的含量x越高，载流子浓度和电导率均增加。颜色对应于的值x = 0（橙色），0.2（洋红色），1（紫色）和2（蓝色）。可以在克里斯蒂娜·弗劳恩霍夫（Christina Fraunhofer），斯特凡·施瓦兹米勒（StefanSchwarzmüller），詹姆斯·L·加迪纳（James L.Gardiner），杰弗里·斯奈德（G.
