Phonon scattering is maximized at a rough interface in Bi‐Te core/shell structure nanowires, which is simply controlled by a conventional sputtering technique and temperature. On page 3414 , Wooyoung Lee and co‐workers report that rough interface Bi‐Te core/shell nanowires exhibit lower thermal conductivities than those of their smooth interface counterparts, while electrical conductivities for these two types of nanowires are similar.
