Abstract: The back-end-of-line (BEOL) process compatibility is one of the advantages of Hf0.5Zr0.5O2 (HZO)-based ferroelectric (FE) among other kinds of HfO2-doped FEs. However, the impact of stress ...

• 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 ...

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 ...

Researchers developed a crystal that inhales and exhales oxygen like lungs. It stays stable under real-world conditions and can be reused many times, making it ideal for energy and electronic ...

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 ...

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 ...

Wearable flexible electronic devices have garnered significant attention due to their stable monitoring capabilities and their favorable interaction with the human body. Strain sensors serve as the ...

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

The discovery of ferroelectricity in materials that are compatible with integrated circuit manufacturing has sparked a wave of interest in ferroelectric devices. Ferroelectrics are materials with a ...

Hafnium oxide thin films are a fascinating class of materials with robust ferroelectric properties in the nanometer range. While the ferroelectric behavior is extensively studied, results on ...

Hafnium oxide-based ferroelectrics have been extensively studied because of their existing ferroelectricity, even in ultra-thin film form. However, studying the weak response from ultra-thin film ...
