摘要: In this paper, the electronic transport in different Z-shape carbon nanotubes containing double knee junction structures on same tube is studied. One consists of (5,5)-(9,0)-(5,5) nano-metal-metal-metal junctions and another (6,6)-(10,0)-(6,6) nano-metal-semiconductor-metal junctions. With nearest-neighbor π-orbital tight-binding model, quantum conductances these are calculated using Landauer formula. The interesting conductance curves provided to exhibit a potential application arena molecular electronics.
