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, ...
Instead of adjusting the charges distributed on electrode atoms at each time step to keep the electrode in an equipotential state in GCD-CPM modeling, in GCD-CCM modeling, the charge on each electrode atom is preset with the same value. The electrode potential is computed accordingly, showing ...
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...
Charge transfer complexes have high molar absorptivities and are produced when one reagent is an electron donor (Lewis base) and the other is an electron acceptor (Lewis acid). Light absorption is based on an electronic transition from the donor to an associated orbital of the acceptor. As a...
as predicted from the free electron model. In Fig.5, the extracted plasmon excitation energies are plotted as function of bothxand\sqrt{x}. At a lower{q}_{\parallel }value of (0.06, 0), the plasmon excitation could be described to be linear withxor\sqrt{x}, with similar degree of ...
~2000! on the interaction of energetic Zn projectiles in partially ionized laser produced carbon targets, and with similar type experiments. Particular attention is paid to the specific contributions of the K and L shell target electrons to electron recombination in the energetic Zn ionic projectile....
This paper reports the electron transport characteristics of carbon/molecule/Cu molecular junctions, where aromatic molecules (azobenzene or AB and nitroazobenzene or NAB) are employed as the molecular component. It is shown that these devices can be made with high yield (>90%), display excellent...
by using an electron energy loss spectroscopy (EELS) technique59,60,61, we revealed a weak correlation between charge dynamic and thickness for identical BiOBr-2.5 platelets, implying that a change in thickness of BiOBr platelets has little effect on the charge dynamic (Supplementary Figs.11–13)...
26. All the measurements were done on freshly cleaved surfaces at a chamber base pressure better than 2 × 10−10 mbar. The ARPES intensity plots measured as a function of photon energy (hν) have been converted to ky assuming the free electron final states68. The raw data (Ekin ...
