Electron transport through an interacting region: The case of a nonorthogonal basis set
, 2005 The formula derived by Meir and Wingreen [Phys. Rev. Lett. {\bf 68}, 2512 (1992)] for the electron current through a confined, central region containing interactions is generalized to the case of a nonorthogonal basis set.

Low energy electron attachment to condensed formic acid [PDF]
, 2008 Dissociative electron attachment to formic acid in the condensed phase is studied using improved mass spectrometric detection of the negative ion fragments. The desorbed yields are measured as a function of incident electron energy in the range between 3

Effect of Grain Boundaries on the Electron Work Function of Ultrafine Grained Aluminum
Reviews on Advanced Materials Science, 2018 The electron work function (EWF) of ultrafine grained (UFG) aluminum structured by high pressure torsion (HPT) has been investigated. For the first time, the dependence of the EWF on the specific length of grain boundaries (or the grain size) for UFG Al ...

Tailoring low energy electron absorption via surface nano-engineering of cesiated chromium films [PDF]
, 2019 In this letter, we demonstrate that improved low energy electron absorption is achieved by suppressing the crystallinity of chromium thin-films grown on W[110], which points to a promising route for achieving highly efficient thermionic energy converters.

Atomic structure and electronic properties of Ce + O films co-adsorbed on Mo(112)
Results in Surfaces and Interfaces, 2023 The atomic structure, stoichiometry and electron work function of Ce + O films co-adsorbed on Mo(112) were studied by low-energy electron diffraction (LEED), Auger electron spectroscopy (AES) and contact potential difference (CPD) methods. The films with

Edge reconstruction in the fractional quantum Hall regime
, 2003 The interplay of electron-electron interaction and confining potential can lead to the reconstruction of fractional quantum Hall edges. We have performed exact diagonalization studies on microscopic models of fractional quantum Hall liquids, in finite ...

Femtosecond single-electron pulses generated by two-photon photoemission close to the work function
New Journal of Physics, 2015 Diffraction and microscopy with ultrashort electron pulses can reveal atomic-scale motion during matter transformations. However, the spatiotemporal resolution is significantly limited by the achievable quality of the electron source.

Vibrationally promoted electron emission from low work-function metal surfaces [PDF]
The Journal of Chemical Physics, 2006 We observe electron emission when vibrationally excited NO molecules with vibrational state v, in the range of 9⩽v⩽18, are scattered from a Cs-dosed Au surface. The quantum efficiency increases strongly with v, increasing up to 10−2 electrons per NO (v) collision, a value several orders of magnitude larger than that observed in experiments with similar
