Abstract
The aim of this article is to provide a systematic evaluation to perform characteristics on the thermal conductivity and thermal rectification of nitrogendoped graphene NDG Two different structural models about nitrogendoped graphene NDG are constructed by considering nitrogen atomic arrangement It indicates that thermal conductivity of the graphene decreases because of Ndoping and different doped configurations Thermal rectification of the triangular singlenitrogendoped graphene SNDG decreases with an increasing temperature However thermal rectification of the parallel various–nitrogendoped graphene VNDG remains unchanged The phenomenon of thermal rectification exits in SNDG It implies that the SNDG might be a potential promising structure for thermal rectifier by controlling the nitrogendoped modelThe authors would like to acknowledge the support of National Natural Science Foundation of China 61076098 the support of National Natural Science Foundation of China 50875115 Innovative Science Foundation for Graduate Students of Jiangsu Province CXLX12 0622 and the Special Natural Science Foundation for Innovative Group of Jiangsu University during the course of this work
