Web14 mrt. 2024 · Amorphous tungsten oxides typically show low near infrared (NIR) light selectivity owing to the overlapped modulation of visible and NIR light originating from ion insertion induced polaronic adsorption, and poor cycling stability due to the ion trapping effects during the repeated ion insertion/extraction. Web1 dec. 2011 · Total sputtering yield of a polycrystalline tungsten surface during bombardment with both atomic N+ and molecular N2+ ions is determined using a highly accurate quartz crystal microbalance technique. The results thus obtained compare well with existing experimental data.
Web15 jun. 2001 · We have measured the radiation from medium-charge-state ions of tungsten in the spectral range from 45 to 70 \AA{}. The ions were produced in an electron beam ion trap (EBIT), and the radiation was observed using a 2-m grazing-incidence spectrometer. Operating EBIT with beam energies between 500 eV and 4 keV allowed us to sample …
