Theoretical investigation on electron transport properties of singlewall carbon nanotube with oxygen molecular absorption
单壁碳纳米管吸附氧分子的电子输运性质理论研究

Electron transport properties of(4,4) single wall carbon nanotube as well as the nanotube with oxygen molecule absorption,are investigated by using first principles analysis.The results show that electron current through the nanotube with oxygen molecule absorption system increases linearly under low bias ranging from 0 to 1.1 V,while the bias is larger than 1.1 V,the current through this system increases slowly.It is also shown that absorbed oxygen molecule brings two kinds of influence on the properties o...
