Phys. Rev. B 80, 155408 (2009) [5 pages]Molecular-dynamics prediction of the thermal conductivity of thin InP nanowires: Similarities to SiReceived 8 January 2009; revised 7 September 2009; published 2 October 2009 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. © 2009 The American Physical Society URL:
