Effect of a Carbon Nanotube on Ballistic Conduction through Single-Quantum-Dot
We will study the competitive effect between the transport of a quantum dot adsorbed to a ballistic channel and laterally coupled to a single-walled carbon nanotube (SWNT). We will use the “tight-binding” approach to analytically write the SWNT Green’s function and the quantum dot will be solved by the atomic method for . We will present curves of the electronic density of states for some different sizes of nanotubes. The results for the conductance curves will be presented as a function of and for different values of n and hopping between the nanotube and the quantum dot.
