Metalorganic chemical vapor deposition of anatase titanium dioxide on Si: Modifying the interface by pre-oxidation

Influences of acids and salts on the crystalline phase and morphology of TiO2 prepared under ultrasound irradiation

“…Thus, it is very important to develop synthetic methods in which the crystalline phase as well as the size and morphology of the TiO 2 nanocrystals can be controlled. Up to now, many methods such as sol-gel [1], hydrothermal [2], microemulsion [3], chemical vapor deposition [4], inert-gas condensation [5], and pulsed laser deposition [6] have been established for the synthesis of TiO 2 with a certain crystalline phase. Among these preparation techniques, the relatively simple sol-gel method is the most widely used.…”

UHV-MOCVD growth of TiO2 on SiOx/Si(111): Interfacial properties reflected in the Si 2p photoemission spectra

“…There are various deposition techniques, e.g. evaporation of metal followed by (plasma) oxidation [7][8][9], sputtering techniques [10,11], pulsed laser deposition [12], chemical vapour deposition (CVD) [13][14][15][16] and atomic layer deposition (ALD) [17,18]. A manufacturing process may also contain pre-and/or post-treatment such as heating/annealing in ambient gases.…”

Fast and Straightforward Synthesis of Luminescent Titanium(IV) Dioxide Quantum Dots

“…Each Ti oxide is also a component in O 1s but the reliable literature data are rather poor for some of the oxides. The elsewhere reported shift in Ti 2p between Ti4+ and Ti3+ is from 1.2 eV [16] up to 1.6 eV [17,18] and between Ti4+ and Ti2+ from 2.4 eV [12] up to 3.1 eV [15]. The reported BE of components varies in the literature due to the calibration process and the charging effect.…”

“…There are also reported binding energies of Ti 2p3/2 and also O 1s for TiO2 at 458.5 eV-530 eV, Ti2O3 at about 455.6 eV-531.5 eV, and TiO at 454.3 eV-531.4 eV [16]. The BE of Ti 2p3/2 for TiO2 is commonly referred to values about 459 eV [17][18][19] and corresponding to O 1s to values about 530 eV [20] or 531 eV [18]. Photoelectrons from Ti 2p are spin splinted to Ti 2p3/2 and Ti 2p1/2 separated about 5.73 eV [17].…”
