Orbital Physics in the Perovskite Ti Oxides

, 2004
In the perovskite Ti oxide RTiO3 (R=rare-earth ions), the Ti t2g orbitals and spins in the 3d^1 state couple each other through the strong electron correlations, resulting in a rich variety of orbital-spin phases.

A Mechanistic Blueprint for Fast, High‐Yield Green Scintillators Using Conjugated Polymer–Nanocrystal Composites

Advanced Functional Materials, EarlyView.
Conjugated polymer–nanocrystal composites are investigated to develop fast, high‐yield green scintillators. The polymer F8BT enables efficient, ultrafast emission, while blends with non‐emitting HfO2 nanocrystals and luminescent CdZnS/ZnS quantum dots reveal distinct sensitization mechanisms.

Vibrational spectra of solid solution series with ordered perovskite structure [PDF]

Journal of Inorganic and Nuclear Chemistry, 1975
I.R. and Raman spectra are reported for the following three systems: Ba2CaMo1−xTexO6, Ba2−xSrxMgWO6 and Ba2Ca1−xMgxWO6. In the first series the internal vibrations of the M6+O6 octahedra do not influence each other. The intensity of ν1 (MoO6) is five times that of ν1 (TeO6).

Critical Role of Polymer Gate Dielectrics on the Charge Carrier Transport in Perovskite Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
Charge transport in 2D tin perovskite FETs is shown to be governed by dielectric interface behavior. Polar polymer dielectrics induce dipolar disorder that localizes carriers, whereas nonpolar polymers suppress trapping and enable superior charge transport, ensuring stable and reliable transistor operation. ABSTRACT Understanding the role of interfaces

Post density functional theoretical studies of highly polar semiconductive Pb(Ti$_{1-x}$Ni$_{x}$)O$_{3-x}$ solid solutions: The effects of cation arrangement on band gap

, 2011
We use a combination of conventional density functional theory (DFT) and post-DFT methods, including the local density approximation plus Hubbard $U$ (LDA+$U$), PBE0, and self-consistent $GW$ to study the electronic properties of Ni-substituted PbTiO$_{3}

Trapped charge driven degradation of perovskite solar cells

, 2016
Perovskite solar cells have shown fast deterioration during actual operation even with encapsulation, but its mechanism has been elusive. We found the fundamental mechanism for irreversible degradation of perovskite materials in which trapped charges ...
