A sensitive and accurate method/ test to predict the lifetime of aluminum oxide used as a tunnel barrier in magnetic random access memory (MRAM) has been devised. The performance of magnetic tunnel junction is dependent upon the lifetime of aluminum oxide. Aluminum oxide has also been used in high dielectric constant gate dielectric MOS devices suitable for high speed applications. This method ...

Nano-graphene oxide was synthesized by the oxidation of graphite powders. The structural nature of the nano-graphene oxide was characterized by a variety of techniques including XRD, TEM, FT-IR and UV/Vis. The functional groups on its basal planes and edges of nano-grahene oxide play important role in catalytic activity. The catalytic activity of nano-graphene oxide was investigated on Crossed-...

zinc oxide nanoparticles have been synthesized by chemical reaction method.  polyvinyl alcohol (pva) composite film filled with nanometric, monodispersed zinc oxide nano particles prepared by pva solution and nanozinc oxide. polymer blend with zno nanoparticle composite film has prepared by casting technique.  the property of nano composites depends greatly on the chemistry of polymer matrices....

An integrated circuit (IC) dimensions continue to decrease, RC delay, crosstalk noise, and power dissipation of the interconnect structure become limiting factors for ultra-large-scale integration of integrated circuits. Modern microcircuits may have eight metal layers, each separated by only 0.1 micrometers. RC delays and cross talk rather than transistor speed are now the major performance li...

Experiments were conducted to compare the annealing of nano-porous aluminum oxide membranes by 2.45 GHz microwave radiation and by conventional (resistive element) furnace heating. The starting material was Al2O3 membranes that were 60 microm thick, 13 mm in diameter, and containing pores of approximately 200 nm diameter. Changes in the porosity and morphology were recorded from digital process...

Near-field scanning optical microscopy (NSOM or SNOM) opens the fascinating opportunity to access the richness of spectroscopic information at a sub-micronic resolution. Shear-force topography coupled to localized spectral information evidence chemical heterogeneity at this challenging spatial scale, which can be crucial to understand the relationship between microscopic features and macroscopi...

Solid-state recycling, which involves the direct recycling of scrap metal into bulk material using severe plastic deformation, has emerged as a potential alternative to the conventional remelting and recycling techniques. Hot press forging has been identified as a sustainable direct recycling technique that has fewer steps and maintains excellent material performance. An experimental investigat...

This study compares the performance of two types capacitive devices, indium tin oxide-aluminum oxide-zirconia aluminum oxide-silicon (IAZAOS) and oxide-hafnium (IAHAOS), as silicon-oxide-nitride-oxide-silicon (SONOS) non-volatile memory (NVM) total dose ultraviolet radiation (UV TD) sensors. Results show that IAZAOS with zirconia oxide charge-trapping layer outperforms IAHAOS hafnium for a UV T...
