Abstract

In view of the discreteness of electric charges in coupled mesoscopic capacitance and inductance circuit, the Coulomb blockade effect is studied by means of the classical Lagrangian canonical transformation and the finite-difference Schrödinger equation. The results show that Coulomb blockade effect is not only related with the component parameters of each circuit, but also with the coupling parameters,which would serve as an insight to understand the characteristics of the quantum in mesoscopic fields. This paper provides a theoretical basis for design of the micro-nano circuits and devices.
