#HfO2 👇👇
$DAL
• HfO2 has a K-constant approximately ~6x higher than SiO2, with one of the highest melting points of any compound, resulting in >1000x reduction in electron leakage through transistors versus SiO2 – underpinning the next generation of high-performing semiconductors1 .
• HfO2 (High Purity) indicative sale price currently at AU $16,297/kg, reflecting its advanced chemical properties, increasing demand in high‑tech applications, and the scarcity of hafnium‑bearing minerals2 .
o Blue Lagoon sampling has confirmed a ~2.7km strike with >2% ZrO2 and >40ppm HfO2 at surface, with potential for Hafnium grades to concentrate further at depth, subject to drilling confirmation.

Presented by @UNIMORE_univ and @LifeAtPurdue researchers, "Reliability of #HfO2-Based #Ferroelectric FETs: A Critical Review of Current and Future Challenges" examines the reliability #physics of HfO2-#FeFETs, and interprets key device-level reliability metrics. #FETs
If you haven’t seen @ProceedingIEEE’s Feb 2023 issue, it's great time to do so. The issue includes reviews of distributed Nash equilibrium in #games, #HfO2-based #ferroelectric #transistors, and overcoming overconfidence errors in #MachineLearning: https://t.co/2pgtfilPel
A group led by Andrew Rappe has uncovered how #HfO2 retains its #ferroelectric phase as an ultra thin film under strain, offering multifunctional computer processors at the #nanometer scale. Explore:
