Layered superionic conductor hosts atomic vibrations that behave like liquids, glasses and crystals
Phys.org ·
The Brief
- Scientists at the Institute of Metal Research, Chinese Academy of Sciences, directly observed phonons with liquid-like, glass-like and crystal-like behaviour coexisting in one crystalline solid.
- The material studied is the layered superionic conductor AgCrSe₂.
- The finding concerns atomic vibrations inside a crystal, not a new device or product.
Why it matters
It shows that a single crystalline solid can host vibrational behaviours normally associated with different states of matter, which may refine how science models heat transport and thermal properties in superionic materials.
