Single-Electron Tunneling Devices
نویسنده
چکیده
Single-electron tunneling devices can detect charges much smaller than the charge of an electron. This enables phenomenally precise charge measurements and it has been suggested that large scale integration of single-electron devices could be used to construct logic circuits with a high device packing density. Here the operation of the two basic types of single-electron tunneling transistors is reviewed. The applications of singleelectron tunneling in precision measurements and in general purpose computation is discussed. Particular attention is paid to the characteristics of single-electron tunneling transistors in the superconducting state.

In this paper, we present the results of single-electron tunneling in two-dimensional (2D) hexagonal closed packed arrays of palladium nanoparticles. After inspecting the emergence of Coulomb blockade phenomena, we demonstrate the possibilities of using these arrays as a single-electron tunneling based hydrogen sensor. We assumed arrays of palladium nanoparticles with diameters of 3.5 and 6...

We analyze the operation of the wireless single-electron logic family based on single-electron-parametron cells. Parameter margins, energy dissipation, and the error probability are calculated using the orthodox theory of single-electron tunneling. Circuits of this family enable quasireversible computation with energy dissipation per bit much lower than the thermal energy, and hence may circumv...
