Ilya Grinberg,D. Vincent West,Maria I. Alvarado Torres,Gaoyang Gou,David M. Stein,Liyan Wu,Guannan Chen,Eric M. Gallo,Andrew R. Akbashev,Peter K. Davies,Jonathan E. Spanier,Andrew M. Rappe +11 more
TL;DR: The ability of KBNNO to absorb three to six times more solar energy than the current ferroElectric materials suggests a route to viable ferroelectric semiconductor-based cells for solar energy conversion and other applications.
Journal ArticleDOI
Post density functional theoretical studies of highly polar semiconductive Pb(Ti 1 − x Ni x )O 3 − x solid solutions: Effects of cation arrangement on band gap
TL;DR: In this paper, a combination of conventional density functional theory (DFT) and post-DFT methods, which include the local density approximation plus Hubbard $U$ ($\text{LDA}+U$), PBE0, and self-consistent $\mathit{GW}$, was used to study the electronic properties of Ni-substituted PbTiO${}_{3}$ (Ni-PTO) solid solutions.
Journal ArticleDOI
Lattice normal modes and electronic properties of the correlated metal LaNiO3
TL;DR: In this article, the authors used density functional theory calculations to study the lattice vibrations and electronic properties of the correlated metal LaNiO${}_{3}$ and showed that the electronic screening effect from the delocalized Ni 3$d$ and O-2$p$ states mitigates the electronic correlations of the Ni cations.
Journal ArticleDOI
