Electromechanical Origin of Phonon Dynamics Exhibiting Tunable Anisotropic Heat Transport in Layered Nanostructures

Youngoh Kim,
Joonmyung Choi

Abstract: Owing to the structural characteristics of 2D layered nanomaterials, anisotropic thermal conductivity is considered an attractive design factor for constructing efficient heat‐transfer pathways. In this study, the electromechanical origin of anisotropic thermal conduction in Ti3C2O2M (M = Li, Na, K) is investigated at the atomic scale using theoretical multiscale analysis. The results demonstrate that the acoustic and optical phonon modes drive interlayer and intralayer heat conduction, respectively. Further, … Show more
