The effect of structural parameters on effective thermal resistance ( R ⁺ ). (a) for different total levels (m), with N = 2, γ = 0.6, and b = 0.35, (b) for different ratios of length (γ), with N = 2, m = 3, and b = 0.35, (c) for different bifurcate numbers (N), with m = 3, γ = 0.6, and b = 0.35 (d) for different power exponents (b) with γ = 0.6, N = 3, and m = 3. The optimum design of branched single-wall carbon nanotubes with m = 2, N = 2 and two different length ratio γ are inserted as background in (a) and (b), respectively.
