(color online) (a) Parallel thermal conductivity κ_|| of twisted bilayer graphene in Fig. 1(b) as a function of rotation angle θ, where the black and red lines represent the cases with and without interlayer coupling. (b) Difference between thermal conductivities Δκ_|| (= κ_|| without coupling −κ_|| with coupling) varying with rotation angle θ. (c) Variations of κ_|| of T-FLGs with θ = 0°, 30°, and 60° with the number of layers. (d) The values of Δκ_|| of T-FLGs with the number of layers.
