论文摘要
我们将研究吸附到弹道通道的量子点的传输，并横向耦合到单壁碳纳米管（SWNT）之间。我们将使用紧密的结合方法分析编写SWNT绿色函数，并将通过原子方法求解量子点非常大。我们将在某些不同尺寸的纳米管中介绍状态的电子密度的曲线。电导曲线的结果将作为EF的函数以及N纳米管和量子点之间跳跃的函数。
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 function and the quantum dot will be solved by the atomic method for U very large. 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 Ef and for different values of n and hopping between the nanotube and the quantum dot.
