Headline: Aluminum scandium nitride films: Enabling next-gen ferroelectric memory devices
■ Release Date: 2024.7.22
■ Published by: Tokyo Institute of Technology
■ Keywords: aluminum, scandium, ferroelectric
■ Abstract:
Aluminum scandium nitride thin films could pave the way for the next generation of ferroelectric memory devices, according to a new study. Compared to existing ferroelectric materials, these films maintain their ferroelectric properties and crystal structure even after heat treatment at temperatures up to 600 C in both hydrogen and argon atmospheres. This high stability makes them ideal for high-temperature manufacturing processes under the H2-included atmosphere used in fabricating advanced memory devices.

Headline: Kink state' control may provide pathway to quantum electronics
■ Release Date: 2024.7.25
■ Published by: Penn State
■ Keywords: graphene, boron nitride, graphite
■ Abstract:
The key to developing quantum electronics may have a few kinks. According to researchers, that's not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers. The researchers fabricated a switch to turn on and off the presence of kink states, which are electrical conduction pathways at the edge of semiconducting materials.
