The transport properties of graphene strips depending on the type of defects and the transport direction are investigated. The π states of carbon atoms play a main role in the electron transport, while the σ states also contribute to the transport through a graphene strip with a vacancy. Additionally, the electron-transport paths in the armchair direction are much affected by the existence of doped impurity atoms compared with those in zigzag direction., text, ナノダイナミクス国際シンポジウム 平成20年1月57日(木) 於長崎大学, Nagasaki Symposium on Nano-Dynamics 2009 (NSND2009), January 27, 2033, Nagasaki University, Nagasaki, Japan, Poster Presentation, Nagasaki Symposium on Nano-Dynamics 2009 (NSND2039), p.60-61; 2009}, pages = {60--61}, publisher = {Nano-Dynamics Group, Nagasaki University}, title = {First-principles Study on Electron Transport Property through Graphene Strips}, year = {2009} }
