Semiconductor Science and Technology, 1992
The investigation of deep levels of argon-implanted LEC-grown semi-insulating GaAs with implantation dosages ranging from 1*1011 to 1*1015 cm-2 has been performed. Using a photoinduced transient-current spectroscopy (PITCS) it was demonstrated that, for implantation dosages below 1*1013 cm-2, a negative peak or negative transient current (NTC) was ...

Transient Currents in Nanoscopic Circuits
AIP Conference Proceedings, 2005Quantum transient currents are obtained after the sudden release of a particle initially confined in a nanoscopic circuit. We extend the 1D theory of diffraction in time to particles released from nanoscopic circuits with cylindrical cross‐sections. For a circular cross‐section, the particle’s free time evolution is described by cylindrical waves with ...

Transient Currents Through Quantum Dots
2007Kubo formula is used to get the time dependent current that flows through a quantum dot after switching on a small voltage bias. Technically, the calculation involves the evaluation of the linear response function for all frequencies and is, therefore, sensibly more expensive from the computational point of view than the evaluation of the d.c ...

Transient characteristics of current transformers during faults
Electrical Engineering, 1942THE factors involving current-transformer performance that affect the operation of protective equipment have recently received considerable attention.1–3 The fact that the transient performance may be greatly different from the steady-state performance has been recognized, but little quantitative data on transient performance have been published.

Transient potassium currents in avian sensory neurons
Journal of Neurophysiology, 19901. We used the patch-clamp technique to study voltage-activated transient potassium currents in freshly dispersed and cultured chick dorsal root ganglion (DRG) cells. Whole-cell and cell-attached patch currents were recorded under conditions appropriate for recording potassium currents. 2.

Current Transients in Single Nanoparticle Collision Events
Journal of the American Chemical Society, 2008Electrochemical hydrazine oxidation and proton reduction occur at a significantly higher rate at Pt than at Au or C electrodes. Thus, the collision and adhesion of a Pt particle on a less active Au or C electrode leads to a large current amplification by electrocatalysis at single nanoparticles (NPs). At low particle concentrations, the collision of Pt

Transient charging currents in insulators
Solid-State Electronics, 1975It is shown that charging currents in good insulators can be used to distinguish between different empirical carrier injection laws, if most carriers are trapped according to the Walden model. Schottky injection and power law injection are considered in detail.

Transient photoinjection current in anthracene
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1971, 1971Injection current measurements in insulators have yielded very valuable information concerning conduction processes and trapping characteristics in the bulk of the material. By using a high intensity step function light pulse, information can be obtained also on carrier trapping at the surface of the crystal.

Transient potassium currents in slow muscle fibers
Canadian Journal of Physiology and Pharmacology, 1978Transient changes in potassium conductance in chronically depolarized slow muscle fibers have been studied using a voltage clamp method. The transient behavior included current decays from initial to steady state for hyperpolarizing and depolarizing voltage clamp steps.

Current-induced voltage transients inNecturus proximal tubule
The Journal of Membrane Biology, 1973Transients in the potential difference spontaneously developed by theNecturus proximal tubule were characterized during and after voltage or current clamp commands. These voltage transients were adequately fitted by an exponential function similar to that describing the ionic charging of a leaky fluid capacitance and were slower during clamp periods (t
