Correlations in coupled layers of electrons and holes
Physical Review B, 1994We investigate interparticle correlations for two layers of charge-carrier liquid trapped in adjacent wells of a gallium arsenide heterostructures. We determine in the absence of appreciable tunneling the static polarizability, the pair correlation functions, and the local-field corrections both within a layer and between the layers.

Electron Microscopic Study of a Slime Layer
Journal of Bacteriology, 1969Slime layers are being studied in our laboratories in an attempt to understand their functions in the control of pollution in natural streams. A method for fixing, staining, and embedding microorganisms in the intact slime has been developed. In this method, epoxy resin discs are placed in a holder and are introduced into a simulated stream.

Polarons in the layered electron gas
Physical Review B, 1991In a layered electron gas, optical phonons which vibrate with their polarization parallel to the c axis are relatively unscreened when the conduction electrons can move only within the planes. We calculate the electron-phonon interaction between the conduction electrons and these parallel phonons. We show that the interaction is very weak.

Electron superconductivity in coupled electron-hole layers
Physical Review B, 1998We investigate superconducting pairing of electrons when coupled to an adjacent layer of holes in a GaAs semiconductor heterostructure. When the density of the electrons is much higher than the density of holes, the repulsive electron-electron interaction is reduced by dynamical coupling to the strongly correlated holes. For the effective-mass ratio of

Electron-electron scattering in silicon inversion layers
Journal of Physics C: Solid State Physics, 1983The authors present the results of an investigation of the rate of electron-electron scattering in the two-dimensional electron gas of the Si inversion layer. The electron-electron scattering rate was extracted by analysis of the negative magnetoresistance in the regime of weak localisation when kFl>1, where kF is the Fermi wavevector and l is the mean

Localization and electron-electron interactions in few-layer epitaxial graphene
Nanotechnology, 2014This paper presents a study of the quantum corrections caused by electron-electron interactions and localization to the conductivity in few-layer epitaxial graphene, in which the carriers responsible for transport are massive. The results demonstrate that the diffusive model, which can generally provide good insights into the magnetotransport of two ...

Electronic structure of layered compounds
JETP Letters, 2006The electronic structure of the intercalated graphite compounds XC6 (X = Ca, Sr, Ba, Yb, and La) has been studied using the linearized augmented plane-wave method. It has been found that the electronic structure of the carbon layers in these compounds is qualitatively different from a two-dimensional graphite structure. A lower critical superconducting-

Shielding by an electron surface layer
Physical Review B, 1978We seek to determine whether the shielding observed in the electron free-fall experiment could be performed by electrons in a surface layer. An idealized model is used to estimate the shielding of the uniform electric field produced by the gravitational compression of the ionic lattice. We allow for the possibility that the charges in the surface layer

Electronic Effects in the Electric Double Layer
Chemical Reviews, 1996All electrochemical reactions take place at the interface between an electronic conductor, the electrode, and an ionic conductor, the electrolyte. Since the course of these reactions and their variation with the electrode potential depend on the distribution of the particles and the charges in this interfacial region, its structure is of paramount ...
