An approach for studying shot noise in mesoscopic systems that explicitly includes the Coulomb interaction among electrons, by self-consistently solving the Poisson equation, is presented. As a test, current fluctuations on a standard resonant tunneling diode are simulated in agreement with previous predictions and experimental results. The present approach opens a new path for the simulation of nanoscale electron devices, where pure quantum mechanical and Coulomb blockade phenomena coexist.

    Spectroscopic measurements are reported of the plasma formed inside a hollow anode (HA) with a ferroelectric plasma source (FPS) incorporated in it. The HA was used as a cathode in a diode supplied by an accelerating pulse (⩽300 kV, ⩽400 ns). It was found that the HA discharge (1.2 kA,...

    Lower Hybrid Current Drive (LHCD) has been demonstrated on Alcator C-Mod. The LH-driven fast electrons can be detected through hard x-ray Bremsstrahlung emission as well as relativistically downshifted electron cyclotron emission (ECE). C-Mod has a hard x-ray camera with 32 chords, as well as...

    A separator of monoenergetic electrons is described, in which two kinds of assemblies of “miniorange”-type magnetic filters (six magnets in each) are used. The 207Bi isotope with an activity of 240 kBq (7 μCi) that emits K 1063 and K 1770 conversion electrons serves as the...

    Relativistic electrons are efficiently generated when multiterawatt lasers focused to ultrahigh intensities >=1019 W/cm2 illuminate the surface of dense plasma targets. A theoretical study finds that during typical picosecond pulse widths, significant amounts of Dreicer produced runaway...

    We study the decay rate and the CP violating asymmetry of the exclusive and decays in the case where one of the final leptons is polarized. We calculate the contributions coming from the individual polarization states in order to identify a so-called wrong sign decay, which is a decay with a...

    The validity of a widely used simple closed-form expression for the recombination associated with dangling bonds in hydrogenated amorphous silicon (a-Si:H) is linked to the relative position of the distribution of the dangling bond states with respect to the quasi-Fermi levels for trapped...

    The excitation of the singlet S and P° levels of a Sr atom from the ground state by slow electrons was studied by the method of extended crossing beams. It was ascertained that perturbations manifest themselves in the behavior of the excitation cross sections in the spectral series arising as...
