Efficient TiO2 Photocatalysts from Surface Hybridization of TiO2 Particles with Graphite-like Carbon
Liwu Zhang,Hongbo Fu,Yongfa Zhu +2 more
TL;DR: In this paper, photoelectrochemical measurements confirm an electronic interaction between TiO2 and graphite-like carbon, and the mechanism of the enhanced photocatalytic activity under UV irradiation is based on the high migration efficiency of photoinduced electrons at the graphitelike carbon/TiO2 interface.

The one phonon Raman spectrum in microcrystalline silicon
H. Richter,Z. P. Wang,Lothar Ley +2 more
TL;DR: In this paper, a relaxation in the q-vector selection rule for the excitation of the Raman active optical phonons was proposed to increase the red shift and broadening of the signal from microcrystalline silicon films.

Electrical properties of titanium dioxide semiconductors
R. G. Breckenridge,W. R. Hosler +1 more
TL;DR: The electrical properties of rutile lattices have been studied for several years as mentioned in this paper, however, the previous studies were only of the electrical conductivity of ceramics so that little information about the properties of the rutiles lattice is available.
