In article number 1906718, Mahmoud I. Hussein, Chia‐Nien Tsai, and Hossein Honarvar provide an in‐depth literature and technical review of nanophononic metamaterials (NPM) and nanophononic crystals (NPC), and their potential impact on thermoelectricity. These nanostructured materials exhibit unique features–nanoresonators in NPMs and periodicity in NPCs–that cause significant reductions in the thermal conductivity. Attention is given to the underlying physics and performance, in contrast to a corresponding standard uniform membrane.
