We have theoretically investigated the role of the interfacial arrangement on the transport properties of finite armchair and zigzag single-walled carbon nanotubes attached to various metallic contacts. We have applied the non-equilibrium Green functional formalism with a Tight-Binding and an Extend

We study the gas molecule adsorption effects on the electrical conductivity of both zigzag (9, 0) and armchair (5, 5) carbon nanotubes. Using the tight-binding model, Green's function technique and coherent potential approximation, it is found that the adsorption of some gas molecules can cause a ch
