Structural and optical properties of titanium oxide thin films deposited by filtered arc deposition

Influence of the growth parameters on TiO2 thin films deposited using the MOCVD method

“…Reports of its high dielectric constant, chemical stability, high refraction index and semiconductor properties motivated research in the growth of high-quality thin films by a variety of techniques including MOCVD [1][2][3], pulsed laser deposition [4], sputtering [5][6][7], solgel [8] and filtered arc deposition (FAD) [9]. There are three types of TiO 2 crystalline structures: anatase, rutile, and brookite.…”

Some Applications of Cathodic Arc Coatings

“…Beginning in the late 1980s, Phil Martin and his group at CSIRO in Sydney, Australia, pioneered the use of filtered arc deposition for nitride and oxide films for optical applications [3,109,110,111,112,113,114,115]. Of special interest are wide band gap materials because they are transparent in the visible part of the optical spectrum.…”

“…Via energetic condensation, even the rutile phase can be synthesized at room temperature, provided the ions are accelerated by biasing to about 100 eV or greater [113,114]. Figure 10.11 shows the refractive index for the various phases of TiO 2 .…”

Preparation of organic-phased TiO2 nanotube array electrode with higher quantum efficiency and its catalytic degradation on Methylene blue

“…[1][2][3][4][5] Several recent studies indicated that TiO 2 -NTs had improved properties compared to any other form of titania for photocatalysis, [6,7] the generation of hydrogen from water splitting, [8,9] solar energy conversion, [10][11][12] the anodes of lithium ion batteries [3,13] sensors for detecting chemical oxygen demands [14] and trace levels hydrogen gas. [15] However, because of its large band gap (3.05eV for rutile and 3.15eV for anatase), [16] the activation of its photocatalytic capability requires ultraviolet light (λ < 400nm) that contributes less than 5% of the total energy of the solar spectrum. [6,17,18] In addition, the low efficiency of electron-hole separation limits the practical application of TiO 2 -NTs in photoelectrochemical and photocatalytic processes.…”
