Dynamic Single-Electron Transistor Modeling for High-Frequency Capacitance Characterization

Applied Sciences, 2022
Based on the time-dependent master equation and taking the dynamic gate current into account, a new single-electron transistor (SET) model is proposed, which can represent intrinsic terminal capacitances and transcapacitances.

Reconfigurable Boolean logic using magnetic single-electron transistors. [PDF]

PLoS ONE, 2015
We propose a novel hybrid single-electron device for reprogrammable low-power logic operations, the magnetic single-electron transistor (MSET). The device consists of an aluminium single-electron transistor with a GaMnAs magnetic back-gate.

Quantum transport in a single molecular transistor at finite temperature

Scientific Reports, 2021
We study quantum transport in a single molecular transistor in which the central region consists of a single-level quantum dot and is connected to two metallic leads that act as a source and a drain respectively. The quantum dot is considered to be under

Effective capacitance of a single-electron transistor [PDF]

Physical Review B, 2008
Starting from the Kubo formula for conductance, we calculate the frequency-dependent response of a single-electron transistor (SET) driven by an ac signal. Treating tunneling processes within the lowest order approximation, valid for a wide range of parameters, we discover a finite reactive part even under Coulomb blockade due to virtual processes.

Bottom‐Up Single‐Electron Transistors

Advanced Materials, 2017
AbstractAs the downscaling of conventional semiconductor electronics becomes more and more challenging, the interest in alternative material systems and fabrication methods is growing. A novel bottom‐up approach for the fabrication of high‐quality single‐electron transistors (SETs) that can easily be contacted electrically in a controllable manner is ...

The Kondo effect in a single-electron transistor [PDF]

Materials Science and Engineering: B, 2001
In our single electron transistor (SET), a droplet of about 50 electrons is separated from two conducting leads by tunnel barriers. A set of electrodes (Fig. 1(a)), on the surface of a GaAs/AlGaAs heterostructure which contains a two-dimensional electron gas (2DEG), is used to confine the electrons and create the tunnel barriers.

Single charge transport in a fully superconducting SQUISET locally tuned by self-inductance effects

AIP Advances, 2022
We present a single-electron device for the manipulation of charge states via quantum interference in nanostructured electrodes. Via self-inductance effects, we induce two independent magnetic fluxes in the electrodes and we demonstrate sensitivity to ...
