Phononic thermal rectifier: a new proposition

Abstract: We put forward a new prescription for achieving a phonon-based thermal rectifier at the nanoscale level, considering a one-dimensional phononic system. The central mechanism relies on the temperature-dependent spring constant along with the presence of mass modulation which essentially breaks the symmetry in the system and thus leads to different thermal currents in two bias polarities. Along with thermal rectification, the phenomenon of negative differential thermal resistance (NDTR) is also observed. The NDT… Show more
