Abstract
We show through calculations on typical lattice models that thermal conductance can well describe the near-equilibrium thermal transport property of one-dimensional materials of finite length, which presents a situation often met in the application of nanoscale devices. The generally contains contributions from the material itself and those from the thermal reservoirs. The intrinsic of the material, i.e., the one with the fewest external influences, can be efficiently calculated with the help of the “blackbody”-like nonreflective thermal reservoir, either through the nonequilibrium method or through the Green-Kubo-type formula. thus calculated would be helpful to guide the design of thermal management and heat control in nanoscale devices.
