We present a technique to calculate the transport properties through onedimensional models of molecular wires. The calculations include inelastic electron scattering due to electron-lattice interaction. The coupling between the electron and the lattice is crucial to determine the transport properties in one-dimensional systems subject to Peierls transition since it drives the transition itself....

Ionization injection triggered by short wavelength laser pulses inside a nonlinear wakefield driven by a longer wavelength laser is examined via multidimensional particle-in-cell simulations. We find that very bright electron beams can be generated through this two-color scheme in either collinear propagating or transverse colliding geometry. For a fixed laser intensity I, lasers with longer/sh...

Tokamak discharges are sometimes terminated by disruptions that may cause large mechanical and thermal loads on the vessel. To mitigate disruption-induced problems it has been proposed that “killer” pellets could be injected into the plasma in order to safely terminate the discharge. Killer pellets enhance radiative energy loss and thereby lead to rapid cooling and shutdown of the discharge. Bu...

We introduce differential-mode hot electron injection for adapting and storing analog nonvolatile signed state variables. This approach is compatible with modern digital CMOS technologies and is readily extended to novel circuit applications. We highlight advantages of the technique by applying it to the design of an adaptive floating gate comparator (AFGC). This is the first use of this techni...

The authors seek to review injection concepts for plasma based acceleration. It is shown that regardless of injection mechanism, resultant beams will be similar due to wave structure. Also, most schemes employ the same basic processes, namely the dephasing of electrons by laser elds, and can thus be analyzed with similar approaches.

The blowout (or bubble) regime of laser wakefield acceleration is promising for generating monochromatic high-energy electron beams out of low-density plasmas. It is shown analytically and by particle-in-cell simulations that self-injection of the background plasma electrons into the quasistatic plasma bubble can be caused by slow temporal expansion of the bubble. Sufficient criteria for the el...

The migration of Au atoms to fill the S vacancies in MoS 2 memristors increases electron injection rate and reduces contact resistance at metal–semiconductor interface, thus causing resistive switch.

Ambipolar carrier injection from gold electrode into pentacene was investigated by time-resolved optical second harmonic generation (TRM-SHG) imaging. Smooth hole injection is verified by rapid decrease of the SHG intensity at the electrode edge, indicating the absence of an injection barrier. In contrast, TRM-SHG results clearly indicated the presence of electron injection from the high-work f...

This paper describes the analysis results of the trench oxide of power devices by means of light emission analysis. Localized electron injection was observed at the upper corners of the trench edges. In addition, it was found that the electron injection into the edge of trench oxide was consistently larger than that into the center of the trench oxide during the electrical stressing. From these...

The effects of solid-state electron injection on the peak amplitude and decay time of photosignal in a ZnO-based homojunction UV photodiode were studied using temporal photoresponse measurements under femtosecond pulses of 355 nm radiation. The injection of about 50 C of charge, carried out by applying forward bias to the junction, resulted in a nearly twofold increase of the peak photoresponse...
