Ballistic Electron Microscopy of Nanographene Layers

Nano Letters, 2008
We use scanning tunneling microscopy and ballistic electron emission spectroscopy and microscopy to study charge transport across Pt-nanographene-Pd interfaces. Four triangle-shaped nanographene molecules with different bulky substituents are studied.

Electronic traps in organic transport layers

physica status solidi (a), 2004
The knowledge about properties of electronic traps in organic semiconductors is one of the major keys for the understanding and optimization of charge transport in organic devices. In the present article the density of occupied states of the most prominent pristine small molecule systems and selected polymers are reported determined, by fractional ...

Static and dynamic properties of coupled electron-electron and electron-hole layers

Physical Review B, 1996
We have investigated coupled layers of electron and hole liquids in semiconductor heterostructures in zero magnetic field for densities ${\mathit{r}}_{\mathit{s}}$\ensuremath{\lesssim}20 using the Singwi-Tosi-Land-Sj\"olander self-consistent formalism generalized for layers of unequal density.

Electron-electron scattering in narrow Si accumulation layers

Journal of Physics: Condensed Matter, 1989
The authors report on measurements of the phase coherence time, tau phi , as determined from the measurement of weak negative magnetoresistance in narrow pinched Si accumulation layers. Under favourable bias conditions, one-dimensional quantum interference and electron interaction corrections to the conductivity are found. The phase coherence length is

Localization and electron-electron interactions in few-layer epitaxial graphene

Nanotechnology, 2014
This 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 ...

Stability of laminar electron layers

The Physics of Fluids, 1984
The stability of a finite thickness, laminar cylindrical shell of electrons rotating azimuthally and enclosed in a coaxial waveguide is considered. The equilibrium rotation of the electrons is supported either by a radial electric field, an axial magnetic field, or a combination of both.

Tunable interstitial anionic electrons in layered MXenes

Journal of Physics: Condensed Matter, 2022
Abstract Electrides with spatial electrons serving as ‘anions’ in the cavities or channels exhibit intriguing properties which can be applied in electron injection/emission and high-speed devices. Here, we report a new group of layered electrides, M2X (M = Ti, V, and Cr; X = C and N) with electrons distributed in the interlayer spacings.

Electron locking in layered structures

Physica B: Condensed Matter, 2000
Abstract We describe a novel state of electrons and phonons arising in layered structures, like cuprates (HTSC) and semiconductor superlattices (SSL) due to electron–phonon interactions (which can be strongly enhanced by a strong magnetic field). These states are characterized by a localization of phonons and a self-trapping [1] , [2] , [3] , [4] ,

Electron Transmission through Molecular Layers

The Journal of Physical Chemistry B, 1998
This article discusses general issues associated with electron transmission through thin molecular films. On the experimental side, we emphasize recent investigations of photoemission through organized organic films adsorbed on metal surfaces. Theoretical and numerical approaches to transmission and tunneling through such films are discussed.
