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...

As circuits are made smaller, certain new physical phenomena will appear. When the capacitance of components becomes so small that adding a single electron to that component causes the voltage to jump significantly, then singleelectron effects will have to be included in the device models. This can have important consequences for the conductance through the device and the noise that is observed...

This work describes the simulation and modeling of current voltage characteristics of polymer light emitting diode. To understand the device characteristics first a single layer organic device with single carrier injection is studied. The simulations are used to clarify the role of barrier height, device thickness and mobility. A new analytical model is developed based on a simple mobility mode...

We show that a quantum wire device with spin splitting can work as an active spin polarizer. Hot electrons in one ‘spin’ subband (e.g. ‘spin-up’) may pass such a device with weak electron pair scattering, while electrons in the opposite subband (‘spindown’) may have high conversion probability into the ‘spin-up’ subband, resulting in spin polarization of a hot electron beam. Under different cir...

Making use of bipolar transport in single-wall carbon nanotube quantum transistors would permit a single device to operate as both a quantum dot and a ballistic conductor or as two quantum dots with different charging energies. Here we report ultra-clean 10 to 100 nm scale suspended nanotube transistors with a large electron-hole transport asymmetry. The devices consist of naked nanotube channe...

We propose a novel semiconductor device in which electronic-analogue dendritic trees grow on multilayer single-electron circuits. A simple cellular-automaton circuit was designed for generating dendritic patterns by utilizing the physical properties of single-electron devices, i.e. quantum and thermal effects in tunneling junctions. We demonstrate typical operations of the proposed circuit thro...

A new type of electrometer is described that uses a single-electron transistor (SET) and that allows large operating speeds and extremely high charge sensitivity. The SET readout was accomplished by measuring the damping of a 1.7-gigahertz resonant circuit in which the device is embedded, and in some ways is the electrostatic "dual" of the well-known radio-frequency superconducting quantum inte...
