摘要

We investigated the thermal conductivity of InP nanowires with diameters d=0.83, 1.66, 2.49, 3.32, 4.15, and 4.97 nm by means of molecular-dynamics simulations using a potential with two-body and three-body contributions. In the temperature range of 100-700 K, thermal conductivities of approximately 1.0-2.5 W/(K m) are predicted-1 to 2 orders of magnitude smaller than the corresponding bulk values, but about 1 order of magnitude larger than those suggested by previous predictions.
