Electron beam ion sources and traps „invited..

The electron beam method of stepwise ionization to highest charge states has found applications in electron beam ion sources ~EBISs! for accelerators and atomic physics collision experiments as well as in electron beam ion traps ~EBITs! for x-ray and mass spectroscopy. A dense and almost monoenergetic electron beam provides a unique tool for ionization, because radiative recombination by slow e...

Electron traps in organic light-emitting diodes

This work presents the effects of electron traps in organic light-emitting diodes using a model which includes charge injection, transport, and recombination. For electron-only devices, the electron current is reduced by the traps for several orders of magnitude at fixed voltage, and the traps strongly increase the transient time. For bipolar devices, due to negative trapped charges, traps enha...

Pure electron plasmas in asymmetric traps*

Pure electron plasmas are routinely confined within cylindrically symmetric Penning traps. In this paper the static and dynamic properties of plasmas confined in traps with applied electric field asymmetries are investigated. Simple analytical theories are derived and used to predict the shapes of the stable noncircular plasma equilibria observed in experiments. Both analytical and experimental...

epl draft Optical traps for electron produced by Pauli blocking

We propose a mechanism to trap electrons in a semiconductor using counterpropagating laser beams. The trapping comes from Pauli blocking between electron and virtual exciton coupled to unabsorbed photons. Electron exchange allows for the possibility of momentum transfer between photon and electron. This leads to a sinusoidal trap for electron with a period determined by the laser beam modulatio...
