Our ability of controlling the growth and interfaces of thin dielectric films on III–V semiconductors by ultrahigh vacuum deposition has led to investigations of gate stacks containing rare earth oxides of Gd2O3 and Y2O3 as alternative high k gate dielectrics for Si. The abrupt interfaces achieved in these gate stacks have enabled the electrical, chemical, and structural studies to elucidate th...

An ultrasound-assisted method was used to prepare gadolinium oxide (Gd2O3)-zeolitic imidazolate framework (ZIF)-8 nanocomposites. The surface morphology, particle size, and properties of the Gd2O3-ZIF-8 nanocomposites were examined using scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, ultraviolet-visible (UV-vis) spectroscopy. synthesized as a catalyst degrade m...

In this study we model the active layer of a conductive-bridging RAM (CBRAM) at the atomic scale. We concentrate our efforts onto a cubic gadolinium oxide c-Gd2O3 doped with a copper atom coming from an electrode (copper-rich) by a redox mechanism. Using ab initio simulations, the formation enthalpies and the specific electronic states related to neutral and charged Cu interstitials are compute...

To improve the infrared emissivity and ablation resistance of HfB2/SiC/TaSi2 coatings for serving in heat flux 4400 kW/m2, with different contents high-emissivity Gd2O3 were prepared using atmospheric plasma spraying. The highest 3–5 μm can reach up to 0.92 at 1273 K when content is 10 vol.%. increase attributed additional electronic transitions induced by oxygen vacancies, which are generated ...

Ti-sheathed MgB2 wires doped with different amount of nanosized rare-earth oxide (Yb2O3, Gd2O3, and Dy2O3) and/or nanosized SiC were investigated. X-ray diffraction patterns suggested the existence of Mg2Si phase due to the SiC addition, while no any phase related to rare-earth oxide could be detected. Strong enhancement of in-field current carrying capability was observed on 2.5 wt.% Yb2O3 dop...

Gd2O3–B2O3 binary glasses with a wide composition range were fabricated using levitation technique, which allowed the Gd2O3 content of to be increased 60 mol %, is much greater than possible conventional melt-quenching techniques. The dependence thermal, optical, and vibrational properties was investigated. glass transition crystallization temperatures decreased slightly in B-rich region increa...
