Coherent phonon transport and minimum of thermal conductivity in LaMnO${}_3$/SrMnO${}_3$ superlattices

Dennis Meyer, Daniel Metternich, Pia Henning +5

In this Letter, we present investigations of thermal transport in (LaMnO${}_3$)${}_n$/(SrMnO${}_3$)${}_n$ superlattices (SLs) with SL periods $\Lambda =2n$ between $2$ and $12$ unit cells. The an…
