High-temperature phase relations of ZrN–ZrO2–Y2O3 ternary system

Journal of Advanced Ceramics, 2018
Zirconium nitride (ZrN) ceramics were prepared via hot pressed sintering (HP) at 1750 °C in N2 atmosphere with ZrO2–Y2O3 as sintering additive. X-ray diffraction was applied to analyze the phase composition of the as-prepared ceramics to study the high ...

Dielectric and Gate Metal Engineering for Threshold Voltage Modulation in Enhancement Mode Monolayer MoS2 Field Effect Transistors

Advanced Materials, EarlyView.
Enhancement‐mode monolayer MoS2 FETs with low threshold voltage are essential for low‐power electronics. The threshold voltage can be tuned by the gate metal work function when the semiconductor/dielectric interface is clean. Interfaces between monolayer MoS2 and ZrO2 or hBN allow effective work‐function modulation of the threshold voltage, in contrast

Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

Advanced Materials, EarlyView.
Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.

Effect of Bath ZrO2 Concentration on the Properties of Ni-Co/ZrO2 Coatings Obtained by Electrodeposition

International Journal of Electrochemical Science, 2018
Ni-Co/ZrO2 composite coatings with different ZrO2 contents have been prepared by electrodeposition. The ZrO2 content was controlled by deploying different ZrO2 particle concentrations in the bath. Micrographs, composition, microstructure, micro-hardness,

High‐Mobility and Low‐Voltage Top‐Gate Transistors Comprising an InSnO–InSnWO Channel Layer and a Polymethyl Methacrylate Dielectric Layer

Advanced Materials Interfaces, EarlyView.
The top‐gate thin film transistors (TFTs) combining the advantages of both the inorganic InSnWO channel layer and the organic polymethyl methacrylate dielectric layer were prepared. The optimized TFTs exhibit excellent performance, including a high mobility (> 60 cm2 V−1 s−1), a low threshold voltage (< 0.50 V; positive value), and robust stabilities ...

Comparative study on corrosion behavior of plasma sprayed Al2O3, ZrO2, Al2O3/ZrO2 and ZrO2/Al2O3 coatings

Transactions of Nonferrous Metals Society of China, 2016
Abstract ZrO2, Al2O3, ZrO2/Al2O3 and Al2O3/ZrO2 coatings were fabricated on low carbon steel using atmospheric plasma spraying technique. The microstructure and phase composition of the as-sprayed coatings were examined by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively.
