(a) Schematic of the thermal conductivity simulation. Heat is added at L/2 and removed at 3L/2 establishing a thermal gradient between the hot and cold regions. (b–d) Different \({\mathrm {(Mo|W)Se_2}}\) systems with different phonon scattering features. (b) Shows a random distribution of \({\mathrm {WSe_2}}\) (red) in a \({\mathrm {MoSe_2}}\) (green) system, corresponding to a 40% distribution of \({\mathrm {WSe_2}}\) in \({\mathrm {MoSe_2}}\). (c) Shows a level 4 fractal heterostructure and (d) shows a periodic \({\mathrm {MoSe_2}}|{\mathrm {WSe_2}}\) superlattice.
