The thermal conductivity of 1 Wm−1K−1 was measured by the differential 3ω method for an SL with a periodicity of 8.8 nm. In addition to x-ray diffraction analysis of the SL crystal structure, smooth interfaces were confirmed by scanning/transmission electron microscopy.2014http://zaguan.unizar.es/record/13328610.1088/0268-1242/29/12/124003http://zaguan.unizar.es/record/133286oai:zaguan.unizar.es:133286SEMICONDUCTOR SCIENCE AND TECHNOLOGY 29, 12 (2014), 124003 [5 pp.]by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
