Simulation of electrical characteristics of one-dimensional quantum dot array

摘要：

A quantum dot array consisting of Au dots was prepared by the linear aggregation technique and assembled between two electrodes. We study the voltage-current characteristic of the quantum dot array using a Non-Equilibrium Greens Function (NEGF) model based on the Keldysh formalism. The results of our simulation and experimental data are compared. The simulated voltage-current curve is in good agreement with the measured data. It shows that the present model can be used to study quantum dot arrays. Furthermore, our results indicate that the electrical characteristics of Au dot array are directly related to the coupling parameters.
