Dielectric properties of TiO2 thin films deposited by a DC magnetron sputtering system

How Should Iron and Titanium be Combined in Oxides to Improve Photoelectrochemical Properties?

“…The electron mobility of TiO 2 in a nanoparticle (NP) film is about 0.01 cm 2 ·V -1 ·sec -1 , which is low compared to the mobility observed in monocrystals of 1 cm 2 ·V -1 ·sec -1 . 17 Accordingly, TiO 2 suffers from two major limitations which compromise high photon-to-hydrogen conversion efficiency: its wide bandgap and its fast electron-hole recombination. Lately, hematite has emerged as a more promising material due to its suitable bandgap of 2.1 eV, which corresponds to a maximum theoretical air mass 1.5 global (AM 1.5 G) photocurrent density of 12.3 mA·cm -2 .…”

Characterisation of oxidised gadolinium film deposited on Si (100) substrate

“…Also the spectrum did not show any distinct peak in the range of 1630-1600 cm −1 that corresponds to HOH bending (or OH deformation vibration "δ") [52]. Thus, it is possible to postulate that the humidityincorporation is in a form of chemisorbed hydroxyl groups, as postulated in [53][54][55] and found experimentally in the work of ref. [29], which studied the oxidation of thin Gd films by XPS.…”

Field ionization effect on hydrogen adsorption over TiO2-coated activated carbon

“…To introduce a dielectric coating to porous activated carbon seems to be a solution to achieve better results. TiO 2 has been widely studied due to its photochemical, catalytic and dielectric characteristics [16,17]. In recent years, it attracted the attentions from researchers investigating in hydrogen storage.…”
