今天我们来简单介绍一种叫做Single-Electron Transistor的东东,很多概念和量子点相关,虽然相关文章有些老,但技术并不过时。 一. 基本概念 1. 单电子充电能 如图一所示,如果我们考虑一个金属岛和两边的极板形成的结构,由于岛和周围环境之间存在电容,因此当我们向岛上放一个电子或拿走一个电子时,体系的能量会升高,升...
PURPOSE: To provide a high-performance single-electron transistor wherein reduction in the size of a quantum dot required to increase an operating temperature and increase in the ratio of a gate capacity required to realize a stable operation to a tunnel capacity are satisfied simultaneously.WADA ...
Single-Electron-Transistor 来自 掌桥科研 喜欢 0 阅读量: 6 作者: CIT Group 摘要: A combination of classical Coulomb charging,electronic level spacings,spin,and vibrational modes determines the single-electron transfer reactions through nanoscale systems connected to external electrodes by tunnelling ...
Coulomb diamond appeared in the differential conductance map of the device at cryogenic temperatures, indicating that the device worked as a single electron transistor. Upon irradiation with UV light, the current showed discontinuous changes. TheI-VSDcurve and differential conductance mapping before and ...
Novel devices like FinFET, nano-electromechanical systems, graphene-FETs and single-electron transistor (SET) offer several advantages over various shortcomings of scaling. The future of IC industry is proposed to be heterogeneous 3D integration of different technologies. A SET is a potential nano ...
To date, no molecular transistor with gain has been demonstrated. In single electron transistors, for every electron put into the transistor one gets almost one electron out of the transistor. These devices therefore have no gain. Gain serves two major purposes in architectures. First it provides...

We have achieved the operation of single-electron tunneling (SET) transistors with gate-induced electrostatic barriers using silicon nanowire metal-oxide-semiconductor field-effect transistor (MOSFET) structures. The conductance of tunnel barriers is tunable by more than three orders of magnitude. By usi...

We have demonstrated the use of the single electron transistor (SET) as an amplifier for a photodetector operated at 20 mK. The unparalleled low input noise of the SET permits the detection of very small numbers of charge carriers generated in a bulk p-type Si substrate. We present data sho...
