Detailed leakage current analysis of metal–insulator–metal capacitors with ZrO2, ZrO2/SiO2/ZrO2, and ZrO2/Al2O3/ZrO2 as dielectric and TiN electrodes

Journal of Vacuum Science & Technology B, Nanotechnology and Microelectronics: Materials, Processing, Measurement, and Phenomena, 2012
ZrO2-based metal–insulator–metal capacitors are used in various volatile and nonvolatile memory devices as well as for buffer capacitors or radio frequency applications. Thus, process optimization and material tuning by doping is necessary to selectively optimize the electrical performance.

Dechlorination of chlorobenzene in subcritical water with Fe/ZrO2, Ni/ZrO2 and Cu/ZrO2

Journal of Environmental Monitoring, 2009
To obtain information about dechlorination of organochlorine compounds in subcritical water catalyzed by metals assisted with ZrO(2), dechlorination of chlorobenzene has been investigated in the presence of Fe/ZrO(2), Ni/ZrO(2) and Cu/ZrO(2) catalysts. The dechlorination efficiency was increased with increasing residence time, temperature and pressure.

Carbon monoxide hydrogenation over ZrO2 and Cu/ZrO2

Journal of the Chemical Society, Chemical Communications, 1993
Sol–gel-derived ZrO2 with a high surface area (> 250 m2 g–1) is found to be very active in CO hydrogenation and unexpectedly produces propan-2-ol with high selectivity; after incorporation of Cu, a methanol synthesis catalyst is produced not only with a higher activity per unit area than Cu/ZnO, but also with an even lower tendency to produce alkanes ...

Fabrication of lightweight ZrO2 fiberboards using hollow ZrO2 fibers

Ceramics International, 2020
Abstract ZrO2 fiberboards with ultra-low densities (0.34–0.40 g/cm3) were fabricated using biomorphic ZrO2 hollow fibers, which have a lower density and better thermal insulation than traditional ZrO2 solid fibers. The effects of sol binder content, sintering temperature, and proportion of solid fibers on the density, microstructure, compressive ...

ZrO2 Aerogels

2011
Mesoporous zirconia aerogels are very interesting materials with important properties used for several applications such as ceramics and catalysis. The textural and structural properties of zirconia aerogel depend on the preparation parameters such as the hydrolysis ratio, the acid and zirconium precursor concentrations, and the gel aging.

MOS devices with tetragonal ZrO2 as gate dielectric formed by annealing ZrO2/Ge/ZrO2 laminate

Microelectronic Engineering, 2011
A Ge-stabilized tetragonal ZrO"2 (t-ZrO"2) film with permittivity (@k) of 36.2 was formed by depositing a ZrO"2/Ge/ZrO"2 laminate and a subsequent annealing at 600^oC, which is a more reliable approach to control the incorporated amount of Ge in ZrO"2. On Si substrates, with thin SiON as an interfacial layer, the SiON/t-ZrO"2 gate stack with equivalent

Preparation and characterization of ZrO2 and SO42−-promoted ZrO2

Materials Chemistry and Physics, 1987
Abstract The acid-base and oxidizing properties and the structures of ZrOn prepared with ammonia or urea and ZrO 2 treated with sulfuric acid or ammonium sulfate have been investigated. The treatment of ZrO 2 with so 4 2− caused the remarkable increases in the phase transition temperature to monoclinic form, the surface area and the acid strength

ZrO2 and Cu/ZrO2 Sol?Gel Materials Spectroscopic Characterization

Journal of Sol-Gel Science and Technology, 2005
Copper-doped zirconia (1% mol) and zirconia powders were prepared by the sol–gel process, using zirconium n-butoxide and copper nitrate as precursors. The resulting xerogels are nanocrystalline and exhibit different properties from the corresponding microcrystalline materials.
