Simulation the Effect of the Defect on the Conductance of Nanowire

摘要：

The effects of a vacancy on the electronic conductance in a finite one dimensional imperfect quantum wire represents by a sequence of delta function potential were discussed. The results show that the peak of the maximum electronic conductance in the forbidden band caused by vacancy will be largely affected if the position of the vacancy changes. And the position of vacancy is found to have a little effect on the position of the maximum electronic conductance in the forbidden region. All these results demonstrate that for one vacancy existing in a nanowire, the electronic conductance in the conduction band will be deteriorated due to destructive interference of electronic waves.
