英文摘要	The thermal conductivity (魏) of suspended graphene membranes made by chemical vapor deposition (CVD) was measured by micro-Raman mapping. Cracks and wrinkles present in these suspended graphene membranes were identified by micro-Raman mapping, and 魏 values and their statistics were obtained on membranes free of such imperfections in a single mapping. Based on this new technique, an average 魏 value of 1875卤220Wm1K 1 at 420K was measured on 26 suspended graphene membranes that were free of wrinkles, 27% higher than the average value measured from 12 graphene membranes with wrinkles. These results suggest that the variation in published thermal conductivity values for suspended graphene samples could, at least in part, be due to the presence or absence of wrinkles. 漏 2012 IOP Publishing Ltd.
