I-V characteristics of the single quantum dot within impurity Anderson model: the role of correlation regime

Charge current through a single quantum dot coupled to a source and drain with an applied bias voltage is studied. The current-voltage characteristics are calculated using our treatment within the Anderson model. The dependence of the current-voltage characteristics on the Coulomb energy, temperature, gate voltage, and magnetic field is examined. A clear dependence of all the practical requirements, functions and parameters considered in our work to describe the electron transport throughout the quantum dot is highlighted. Our results can be experimentally realized and it is easy to tune practical parameters to determine the correlation regime for a certain spin.
