Er 2 O 3 as a high-K dielectric candidate

Applied Physics Letters, 2007
Erbium oxide (Er2O3) films have been deposited by metal organic chemical vapor deposition on Si(001) using tris(isopropylcyclopentadienyl)erbium. The impact of Si surface passivation by the metal organic prior growth initiation was investigated. The correlation between the Er2O3 films structure, the optical response, the static dielectric constant (K),

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam

Advanced Engineering Materials, EarlyView.
Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

Dielectric breakdown mechanism of Hf -silicate high-k gate dielectrics.

IEEJ Transactions on Sensors and Micromachines, 2004
Dielectric breakdown mechanism of Hafnium (Hf) silicate film has been discussed, on the basis of the temperature dependence of the charge-to-breakdown (Qbd). It has been found that the activation energy of Qbd as a function of reciprocal temperature was around 0.1 eV, irrespective of the injection direction of electrons.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
