A tunable, dual mode field-effect or single electron transistor

Tunable graphene single electron transistor.

We report electronic transport experiments on a graphene single electron transistor. The device consists of a graphene island connected to source and drain electrodes via two narrow graphene constrictions. It is electrostatically tunable by three lateral graphene gates and an additional back gate. The tunneling coupling is a strongly nonmonotonic function of gate voltage indicating the presence...

Modeling and Simulation of a Molecular Single-Electron Transistor

In this paper, to understand the concept of coupling, molecule density of states that coupled to the metal electrodes will be explained then, based on this concept, a weak and strong coupling for the molecules attached to the metal electrodes will be described. Capacitance model is used to explore the connection of addition energy with the Electron affinity and the ionization energy of the mole...

Single-electron Coulomb blockade in a nanometer field-effect transistor with a single barrier

The first experimental study of a new nanometer field-effect transistor with a single barrier in its one-dimensional channel is presented. At low temperatures and as charge density in the channel was varied, nine reproducible periodic oscillations of conductance, in addition to 2e2/h conductance plateaus, were observed before the onset of the first 2e’/h conductance plateau. It was found experi...

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 M...
