چکیده
Tailoring electrical and mechanical properties in the fluorite oxides family is of great interest for technological applications. Other than doping substitution, entropy-driven stabilization an emerging technique new solid solutions formation enhancing or exploring functionalities. However, there a high number possible combinations higher-order diagram investigations, current state art shows limited possibilities predicting phase related properties. In this paper, we expand compositional space ZrO2-HfO2-CeO2-Nb2O5-RE2O3 systems. X-ray diffractometry scanning electron microscopy measurements showed cubic fluorite-type structures when processing compositions at 1600 °C.

متن کاملStudy of the R-(Zr,W)-(O,N) (R = Y, Nd, Sm, Gd, Yb) oxynitride system
The replacement of tantalum by the couple Zr/W within the RTa-O-N systems (R = Y, Nd, Sm, Gd, Yb), enables the preparation of novel oxide and oxynitride phases in the R-Zr-W-O-N system. R2Zr2-xWxO7+x oxides exhibit the fluorite-type (x<0.9) and scheelite (x 1) structures. Corresponding oxynitride compositions are of the fluorite type and show different colors, for example in the case of ytter...
متن کاملGd-doping of HfO2
An increase in the density of states between the oxygen 2p bands and the Fermi level is seen with increasing Gd concentrations. In addition, for the Gd-doped HfO2 films, the Gd 4f photoexcitation peak at 5.5 eV below the valence band maximum was identified using resonant photoemission. Electrical measurements show pronounced rectification properties for lightly-doped Gd:HfO2 films on p-Si and f...

Polycrystalline uranium-bearing compounds Y6U1O12, Gd6U1O12, Ho6U1O12, Yb6U1O12, and Lu6U1O12 samples were irradiated with various ions species (300 keV Kr, 400 keV Ne, and 100 keV He) at cryogenic temperature ( 100K), and the microstructures were examined following irradiation using grazing incidence X-ray diffraction and transmission electron microscopy. The pristine samples are characterized...
متن کاملElectronic structure differences in ZrO2 vs HfO2.
Although ZrO2 and HfO2 are, for the most part, quite similar chemically, subtle differences in their electronic structures appear to be responsible for differing MO2/Si (M = Zr, Hf) interface stabilities. To shed light on the electronic structure differences between ZrO2 and HfO2, we have conducted joint experimental and theoretical studies. Because molecular electron affinities are a sensitive...
