| Abstract Scope |
Two-dimensional materials with a relative twist between adjacent layers form moiré interference patterns whose periodicity greatly exceeds that of the constituent crystal lattices. These systems exhibit a wide range of emergent phenomena arising from moiré-dependent electron correlations and nontrivial band topology. Despite extensive studies of their electronic properties, the influence of strain on their thermal transport remains poorly understood. Here, we investigate strain-dependent thermal transport in twisted graphene and MoS₂, demonstrating that strain-induced atomic reconstructions govern heat transport pathways and their efficiency. We show that the formation and evolution of coherent interfaces play a dominant role in determining the overall thermal conductivity of these structures. These findings establish strain as an effective means of tuning thermal transport and provide a pathway toward thin-film materials with mechanically switchable thermal properties. |
