Single Electron Transistor: A Review

The goal of this paper is to review the physics of Single Electron Transistor (SET) and also the recent trends involve in fabrication of SET. The paper focuses on the application of SET in charge sensing, memories, logic families etc. Paper also briefs about the simulation of SET by TCAD, SIMPLORER, and SIMAN. SET are promising candidate for replacement of conventional CMOS and also following Moore Law. Even if this replacement does not happen, Single electronics will continue to play an important role by shedding light on fundamental size limit on new electronic devices. Moreover, research in this field has generated many novel ideas which may revolutionize Random-access-memories and Digital-data-storage technologies[1].
