Surface-Charge Transport in a Multielement Charge-Transfer Structure

Journal of Applied Physics, 1972
A two-phase 14-stage transfer shift register has been built and operated which uses the surface-charge transistor structure to effect the transfer of signal charge from one stage to the next. This paper describes the structure and presents preliminary experimental results which characterize its operation as a digital shift register.

Charge stripe structure in FeTe

Physica B: Condensed Matter, 2012
Abstract We report the STM study on a single-crystalline sample of FeTe at 7.8 K. FeTe is one of the iron-based superconductor. We measured the resistivity and the magnetization of FeTe. FeTe shows SDW transition at 58 K on these measurements. We study the electronic state of FeTe by using STM/STS for observing FeTe from a microscopic viewpoint.

DNA structure: cations in charge?

Current Opinion in Structural Biology, 1999
Recent X-ray diffraction, NMR spectroscopy and molecular mechanics results suggest that monovalent cations selectively partition into the minor groove of AT-tracts in DNA. These observations are consistent with DNA deformation by electrostatic collapse around areas of uneven cation density.

Charge Collection in Multilayer Structures

IEEE Transactions on Nuclear Science, 1984
Charge collection measurements using energetic ions have been performed on layered structures in bulk and epitaxial silicon. Both fast transient digitizer and slower charge sensitive preamplifier measurements have been made as a function of bias, ion type, energy, and angle of incidence.

Charge structure of the neutron

Il Nuovo Cimento A, 1976
The Clementel-Villi (CV) model used earlier for the proton is now extended to study the charge structure of the neutron. Satisfactory results are obtained for small values ofq2. For large values ofq2, where the CV model fails, a modified CV model for the nucleon is suggested. It is found that for the neutron the modified CV model explains the available

Structure and Thermodynamics of Charged Colloids

1992
A multi-component MSA with non-additive radii (NAR-MSA) is applied to the study of monodisperse polyelectrolyte suspensions, described within the primitive model. The NAR-MSA is analytically solvable, and in practice permits an easy implementation of a rescaled MSA (RMSA).

Charged Dust Structures in Plasmas

2006
Recent advances in the study of collective effects and particle motions in plasma-dust crystals, ordered structures that form in the cathode sheath region of low temperature gaseous discharges, are presented. Plasma collective processes influence the arrangements and vibrations of dust particles in these Coulomb-lattice structures. One important effect

Topological charges of dissipative structures

Soviet Physics Journal, 1988
A scheme is proposed for the analysis of spatially inhomogeneous periodic and quasiperiodic structures, with respect to time, by using the facilities of homotopic topology. The concept of topologically stable (and unstable) dissipative structures is introduced. Dissipative defects that are the analogs of defects of ordered media are investigated within

Geometric structure of charged fields

Physical Review D, 1977
The concept of parallel transport is generalized. It leads to a geometric structure of charged fields. A quantization principle of charge is put forward and the Aharonov-Bohm effect is interpreted within the framework of a one-valued field representation and superposition principle.

Trimethylammoniodiformylmethylide: Structure and charge distribution

Collection of Czechoslovak Chemical Communications, 1980
Geometric arrangement of trimethylammoniodiformylmethylide (I) and charge distribution in this compound were calculated by quantum chemical methods (EHT, CNDO/2, INDO, PCILO, MINDO/2, ab initio). Total energy minimum was found for the arrangement If. The experimentally found dipole moment agrees very well with that calculated for this conformation.
