Sulfur-doping of rutile-titanium dioxide by ion implantation: Photocurrent spectroscopy and first-principles band calculation studies

It is the hot point of the present study to obtain the metal titanium by using the carbon-titanium-oxygen electrolysis. The electrical conductivity, melting point and hardness of C-Ti-O have great influence on the feasibility of electrolysis process. In this paper, the conductivity of rutile titanium dioxide, carbon replacement solid solution (20%, 50%, 80%) and titanium carbide are calculated by first principles. It was found that the more carbon substituted rutile titanium dioxide, the better its conductivity. The electrical conductivity of objects are changed from semiconductors to good conductors. The experimental results show that the conductivity of the experimental results is higher than that of the calculated ones, which may be due to the existence of a large number of hole-excited elements.

AbstractWe present result following localized ion implantation of rutile titanium dioxide (TiO2) using anodic porous alumina as a mask. The implantation were performed with 100 keV56Fe+ions using a fluence of 1.3·1016ions/cm2. The surface modifications where studied by means of SEM, AFM/MFM and XRD. A well-defined hexagonal pattern of modified material in the near surface structure is observed. Local examination of the implanted areas revealed no clear magnetic signal. However, a variation in mechanical and electrostatic behavior between implanted and non-implanted zones is inferred from the variation in AFM signals.

First Principles Study

We present a multiscale computational approach for the first-principles study of bio-nano interactions. Using titanium dioxide as a case study, we evaluate the affinity of titania nanoparticles to water and biomolecules through atomistic and coarse-grained techniques.
