Preparation and Characterization of Ni-Doped TiO2 Materials for Photocurrent and Photocatalytic Applications
Ibram Ganesh,Abhishek Gupta,Polkampally P. Kumar,P. S. C. Sekhar,K. Radha,G. Padmanabham,G. Sundararajan +6 more
TL;DR: Characterization results suggest that as a dopant, Ni stabilizes TiO2 in the form of anatase phase, reduces its bandgap energy, and adjusts its flat band potentials such that this material can be employed for photoelectrochemical oxidation of water reaction.

Band gaps from the Tran-Blaha modified Becke-Johnson approach: a systematic investigation.
TL;DR: This work investigates the performance of the TB-mBJ potential for the description of electronic band structures in a comprehensive set of semiconductors and insulators and proposes to combine it with the Hubbard U correction for localized d∕f states, which is able to provide overall good descriptions for both the band gaps and semi-core states binding energies.
