AbstractAbstract
[en] When the gate length of MOSFETs is scaled into sub-100 nm, the Coulomb-blockade effect will severely affect the trapping processes of acceptor-like oxide traps, which leads to a relative large deviation of the RTS noise time-constant model from conventional Shottcky–Read–Hall (SRH) theory. The Coulomb energy of the trapping process increases with gate bias VGS, and large errors will be introduced to the extracted trap parameters based on the ratio τ-barc/τ-bare of RTS noise when the Coulomb-blockade effect was neglected in a nano-MOSFET

AbstractAbstract
[en] It is found that Hall's correction term exactly cancels another electrostatic term in the total energy of the Wigner solid. Although Hall's correction is appropriate for the calculation of the potential at the Wigner lattice site, it is Fuchs' expression which should be used in the total electrostatic energy of the Wigner solid. The origin of the controversy is clarified using physical arguments, and a simpler derivation of Hall's term is presented

AbstractAbstract
[en] Quasiparticle gaps and exciton Coulomb energies of H-passivated spherical Si nanoshells are computed using first principles SCF and GW methods. We nd that the quasiparticle gap of a nanoshell depends on both its inner radius R1 (weakly) and outer radius R2 (strongly). These dependences on R1 and R2 are mostly consistent with electrostatics of a metallic shell. We also nd that the unscreened Coulomb energy ECoul in Si nanoshells has a somewhat unexpected size dependence at fixed outer radius R2: ECoul decreases as the nanoshell becomes more conning, contrary to what one would expect from quantum confinement effects. We show that this is a consequence of an increase in the average electron-hole distance, giving rise to reduced exciton Coulomb energies in spite of the reduction in the confining nanoshell volume.

AbstractAbstract
[en] Dense dust structures have been observed in a glow DC discharge in neon at a temperature of 77 K. Dependencies of shape, axial and radial sizes of dust structures on discharge current, gas pressure and longitudinal electric field have been studied. At the intersection points of dependencies of radial and axial sizes of dust structures on discharge current, the Coulomb balls have been observed at pressures between 0.15 and 1.2 Torr. The correlation between the discharge parameters, at which Coulomb balls form, and their size, composition, phase and dynamic state of components has been revealed. (paper)

AbstractAbstract
[en] The use of the density functional formalism for obtaining parameters of model Hamiltonians is discussed. These parameters are renormalized quantities, taking effects into account which are not explicitly included in the model. Some renormalization effects of this type are discussed. Methods for calculating Coulomb integrals U are presented, and the renormalization due to screening effects is calculated. The on-site screening is found to be very efficient for Ce, while it is much less efficient for 3d metals. The calculation of hopping matrix elements V is discussed, and renormalization effects due to different Coulomb interactions are considered. Some applications to Ce and 3d systems are presented.

AbstractAbstract
[en] The Coulomb energy of a uniformly charged circular torus is expressed by a fast converging series in term of toroidal functions. A very simple approximate expression has been deduced. This expression has enough accuracy for any application to nuclear physics. A critical fissility x approximately 1.11 is found above which spherical nuclear drops are unstable towards toroidal deformations. (author)

AbstractAbstract
[en] An interpretation is given of the structures of the distribution of mass and total kinetic energy (TKE) in the cold fission of U-234 and U-236 in terms of the energy of the coulomb interaction (C) in the scission. The maximum value of C(Cmax) corresponding to the most compact configuration is interpreted in relation to various fragmentations of mass. It is shown that Cmax increases of the asymmetry of the load increases to a primary fragmentation maintaining the same value of Q. This dependency produces oscillations with a period of 5 uma of the maximum value of C as a function of the mass of the light fragment, which are correlated with the oscillations observed in the maximum value of TKE. Furthermore, it happens that the yield of the most asymmetric fragmentations (corresponding to the most compact configurations) increases
