The Cover Feature shows the single phase of α‐Cu 2 Se 1− x Te x ( x =0.02 and 0.04), which was synthesized by a chemical solution method at room temperature followed by cold pressing and sintering at 650 °C for 6 h in a flowing gas mixture of 20 % H 2 and 80 % N 2 . Cu 1.96 Se 0.96 Te 0.04 exhibits zT ≥1.4 at T ≥920 K. More information can be found in the Full Paper by F.‐H. Lin and C.‐J. Liu.
