• Ferroelectric–Nonferroelectric Transition: When the capacitor size is reduced to 3.85 μm, ferroelectricity vanishes and an ultrahigh dielectric permittivity of 1466 emerges, without requiring ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Scientists in South Korea and Japan created a man-made crystal (SrFe0.5Co0.5O2.5) that absorbs and releases oxygen repeatedly at moderate temperatures without breaking down. The discovery could ...

Scientists develop of a special type of crystal with oxygen breathing abilities, which could be used in clean energy technologies and next-generation electronics. A team of scientists from Korea and ...

Here’s the juicy part: crank the heat to about 400 °C and the crystal lets go of oxygen. Cool it down or swap in a different gas, and it soaks oxygen right back up. What’s wild is you can do this back ...

CEA-Leti research engineers demonstrated for the first time a scalable hafnia-zirconia-based ferroelectric capacitor platform integrated into back-end-of-line (BEOL) at 22nm FD-SoI technology node.

This breakthrough, reported today at the IEDM 2024 conference, represents a major advance in ferroelectric memory technology, significantly advancing scalability for embedded applications and ...

Abstract: We investigate the physical origins of endurance fatigue in silicon channel-based ferroelectric field-effect transistor (Si FeFETs) with TiN/Hf0.5Zr0.5O2/ SiOx/Si gate-stacks. Our study ...
