Investigating the effect of quantized confining energy on the quantum coulomb blockade phenomena in single-electron transistor

Abstract

Metal single-electron transistor (SET) and semiconductor quantum dot (QD) are Coulomb blockade (CB) devices having applications in quantum and classical technologies. The quantized confined energy of the confining system increases when the size of this system decreases. This behavior affect transport of charge carrier through SET significantly. This paper presents the results of investigation on the effect of quantized confining energy on the operation conditions of the single-electron transistor, known as quantum Coulomb blockade phenomena. Moreover, modified mathematical description of operation conditions and the quantum Coulomb blockade region of SET has been presented.
