| Abstract Scope |
Two-dimensional materials with a twist between layers exhibit a moiré interference pattern with a larger periodicity than any of the constituent layer unit cells. In these systems, a wealth of exotic phases appear that result from moiré-dependent many-body electron correlation effects or non-trivial band topology. However, the effect of strain on the thermal performance of these structures is not well understood. Here we examine the effect of strain on thermal transport of graphene and MoS2 and show how atomic configurations control thermal transport paths and their effectiveness. We find that coherent interfaces are key determining factors in the overall thermal performance of these structures. The results of this work can enable breakthrough thin films with switchable thermal performance controlled by strain. |
