Electrical characterization of titanium-based ohmic ...

We report on titanium-based ohmic contacts (titanium carbide, titanium tungsten, and titanium) on both highly doped epilayers (n + and p +) and Al-ion-implanted layers.The TiC contact layer was epitaxially grown on epilayers as well as an Al-ion-implanted layers of 4H-SiC by co-evaporation Ti and C 60 under an ultra-high vacuum condition at low temperature (<500 °C).

A Titanium(IV)‐Based Metal–Organic Framework …

While titanium‐based metal–organic frameworks (MOFs) have been widely studied for their (photo)catalytic potential, only a few Ti IV MOFs have been reported owing to the high reactivity of the employed titanium precursors. The synthesis of COK‐47 is now presented, the first Ti carboxylate MOF based on sheets of Ti IV O 6 octahedra, which can be synthesized with a range of different linkers.

Theory of Carbon Doping of Titanium Dioxide | …

2019-5-26 · Recent experimental studies have determined that carbon doping dramatically improves the photocatalytic activity of TiO2 in the visible-light region. Using density functional theory (DFT) calculations within the generalized gradient corrected approximation, we investigate various structural models of carbon impurities in both the anatase and rutile polymorphs of TiO2 and analyze the associated ...
