V-doped TiO2 thin films were grown by laser ablation on LaAlO3 substrates. In the chosen range of the growth conditions, all V:TiO2 films have an anatase structure and exhibit semiconducting and ferromagnetic behaviors at room temperature. V:TiO2 films have a giant magnetic moment and they seem to be far better ferromagnetic than Co/Fe/Ni-doped TiO2 films. This study has proved that a few percent of V substituting for Ti in TiO2 can result in a potential diluted magnetic semiconductor. © 2004 American Institute of Physics.

    Room temperature ferromagnetic Fe- and Ni-doped TiO2 thin films were grown by the laser ablation on both LaAlO3 and SrTiO3 substrates. Most of the films are pure anatase, and only the films of Ni content of 3.6% and 4.6% are rutile. Films on LaAlO3 substrates are more crystallized than films on...

    Abstract. Pure titanium dioxide (TiO[sub 2]) thin films were deposited on single-crystal Si(100) substrates by laser ablation. We investigated the effects of ambient gas (O[sub 2] or Ar), pressures, and substrate temperatures on film quality. From the annealing experiment of the deposited...

    Degradation of salicylic acid (SA) with thin film photocatalyst, titanium dioxide (TiO2) and nitrogendoped TiO2 (TiO2-x-Nx) combined with ultraviolet (UV) radiation was studied. TiO2 film with thickness of 15 and 65nm was tested. The TiO2-x-Nx film had thickness of 15nm on top of TiO2 (50 nm)....

    The resistance switching mechanism of TiO2 films under voltage sweep mode was investigated. From the observed soft set of Pt/TiO2/Pt sample and from the polarity-dependant switching behavior of Ir(O)/TiO2/Pt sample, local rupture and recovery of conducting filaments near the anode interface wer...

    The article presents a response to the comment on a previously published article "A transparent metal: Nb-doped anatase TiO2." The comment claimed that the conductivity of Ti1-xNbxO2 originates from Sr(Ti, Nb)O3 at the interface due to Nb diffusion into the SrTiO3 substrate. They reconfirm that...

    We report on the successful growth of amorphous TiSiO[sub x] thin films by means of pulsed-laser ablation of a TiO[sub 2]/SiO[sub 2] composite target in a high-vacuum chamber. The room-temperature resistivity of the TiSiO[sub x] films is found to decrease by more than 6 orders of magnitude...

    Mn was doped into TiO2 to clarify the real effects of Mn doping on magnetic and structural properties of TiO2 thin films. Mn doping does not play any key role in introducing ferromagnetism (FM) in the system. When the dopant concentration is small (below 5%), the Mn atoms can still be...
