Description
Summary:A theoretical study of the dynamical mechanism of Coulomb blockade using the totally asymmetric simple exclusion process (TASEP) consisting of only one site has been laid down in [1]. Coulomb blockade is the main idea behind the so-called quantum dot, which is a product in the advancement of nanotechnology. A quantum dot is a nano-scale system, which consists of only one electron. It offers exciting opportunities in the creation of semiconductor fabrication technology. In this study, a further examination is conducted into the relationship of the Coulomb blockade and the TASEP by obtaining numerical results of the density and current density of the electron trapped inside the dot as well as the tunneling of the electron through the dot. The results show that the density and current density agree with the electron being trapped inside the dot with high density and low current density, and the electron passing through the dot with a moderate value of the density and current density.
