In article number 1907286, Xiaojia Wang, Sokrates T. Pantelides, and co‐workers discover that single‐crystalline hafnium pentatelluride (HfTe 5 ) possesses strong thermal anisotropy owing to its quasi‐1D asymmetrical structure. The original factors contributing to its substantially higher thermal conductivity along the b‐axis (≈0.42 W m −1 K −1 ) than the previously reported record‐low thermal conductivity (≈0.33 W m −1 K −1 ) of zirconium pentatelluride are revealed. This work could guide the design and engineering of high‐efficiency new directional thermal management for various applications.
