Total thermal conductance K as a function of the length d of the scattering region for different radii r ₂ at the temperature controlled area. Panels (a) and (b) correspond to T = 0.2 K and T = 2 K. Curves a , b , and c are for r ₂ = 10, 15, and 5 nm, respectively. Solid and dashed curves correspond to the scattering region with material GaAs and AlAs. Here, we take r ₁ = 10 nm.
