Optical and semiconductive properties of binary and ternary thin films from the Nb-Ti-O system

Niobium oxide promoted with alkali metal nitrates for soot particulate combustion: elucidating the vital role of active surface nitrate groups

“…Different kinds of oxygen species are detected on the surfaces of the catalysts. In detail, the peak at ∼529.8 eV is attributed to the lattice oxygen (O latt ) in Nb–O, 50,58,69 and the peak at ∼531.5 eV is attributed to the chemically adsorbed oxygen species (O ads ) on the catalyst surfaces, 50,58,69 which are observed in all the catalysts. Nevertheless, besides these two kinds of oxygen species, on the XPS spectra of KNb1-9 and CsNb1-9, an additional oxygen peak at ∼532.3 eV is observed, which can be attributed to the oxygen species in the NO 3 − groups.…”

Nanostructured CeO2 ultrathin film deposited by the Langmuir Blodgett technique for highly sensitive and specific detection of sub ppm level NO2 gas at room temperature

“…52 The conduction type of the ultrathin CeO 2 film has been further verified by the Mott-Schottky plot, i.e., 1/C 2 vs. applied potential (C is the space charge layer capacitance) using an electrochemical cell containing 0.1 M KCl electrolyte. 53 The negative slope of the film as shown in Fig. S3 (ESI †) indicated ptype conductivity of the CeO 2 ultrathin film.…”

Optical Losses of Frontal Layers in Superstrate CdS/CdTe Solar Cells Using OPAL2

“…In respect to software equations and TMM method coding, these fringes are related to the implementation of the scattering effects due to the difference of the refractive index values at the interfaces [64,65]. Changes in thickness resulted in the reflectance curve having different interference fringe patterns attributed to the carrier density change in various thickness ranges [66]. If the carrier concentration rises, the height of the absorbing band increases in contrast to the half-width value related to the absorption band's diameter that declines with thickness, and the absorption curve peak moves through shorter wavelengths for thinner samples [16].…”
