Abstract

Non-equilibrium molecular dynamics calculations were performed in order to obtain the thermal conductivity coefficients of InSb nanowires in comparison with the bulk system value. For bulk, the value obtained was 16 ± 2 Wm−1 K−1 which is in very good agreement with experimental value of 15 Wm−1 K−1, and the thermal conductivity of the nanowires were 0.54 ± 0.01 Wm−1 K−1 and 0.50 ± 0.01 Wm−1 K−1 for a 5 and 4 unit cells square cross-sectional nanowires, respectively, which is almost two orders of magnitude smaller. This result is in agreement with other simulations performed for other materials.
