In order to separate valence and core electron charge densities, one needs an electron probe size that is much smaller than the 1 Å feature size of valence electron orbitals. Achieving this experimentally is currently challenging as state-of-the-art probes are on the order of valence electr...
Interactions among heat ux from plasma, surface temper- ature, and thermo-electron emission are simulated considering self-consistency among electron transport, deposited heat and material thermal response for Be, C, Mo and W under the condition of plasma temperature Te 40 eV, ...
We report on the propagation of electron beams generated by a niobium photocathode illuminated by different wavelength excimer lasers. The cathode used was a polycrystalline disc. Its work function was 4.3 eV while the laser photon energy was 4.02 eV for the XeCl laser and 5.6 eV for the KrCl...
In contrast to thermocatalysis, electrocatalysis involves the transfer of electrons and protons which electrochemical potentials needs to be calculated. The Computational Hydrogen Electrode (CHE) approach considers entirely proton-coupled electron transfer (PCET) steps and derives these electrochemical potential...
Insertion electrochemical electrodes exhibit simultaneous electron and ion transfer, with the two transfers proceeding across different interfaces. Herein ... B Pranszke 被引量: 0发表: 2010年 THE FUNCTION OF NEUTRAL‐IMPURITY AND ALLOYED‐POTENTIAL ELECTRON SCATTERING IN EXCITATION OF SPACE‐CHARGE WAVES...
A charge transfer state is an excited state in which electrons are moved from one molecular unit to another, either partially or completely, resulting in the redistribution of electron density. This state is characterized by intense transitions in the UV/Vis range, broad bands, solvatochromic shifts...
A computer simulation of the electron trajectories reveals that degradation in resolution and throughput at higher energies can be traced to the chromatic aberrations of the acceleration region just past the drift region. 展开 DOI: 10.1063/1.1144320 被引量: 3 ...
(3D) plasmons, which reflect the nature of the electronic structure and Coulomb repulsion on both short and long lengthscales. With increasing electron doping, the plasmon excitations increase monotonically in energy, a consequence of the electron correlation effect on electron structure near the Fermi...
Long-lived charge carriers are necessary to initiate redox reactions on photocatalyst surfaces. The ideal photocatalyst should have charge carriers with fast mobility and low recombination rates, or good “charge carrier management”. Being able to predi
1b for indirect transitions (based on the data from Raman and absorption spectroscopy). Excited electron−hole pairs, in the proximity of the strained area, are funnelled towards the electrodes by the built-in energy gradient, giving an enhanced photoresponse13,18. For Vsd = 0 V, ...
