Liquid-like cationic sub-lattice in copper selenide clusters
Copper selenide is super-ionic only at high temperatures. Here, the authors discover room temperature super-ionic behaviour in ultrasmall clusters of Cu2Se—but not in its larger or bulk forms—owing to an unusual liquid-like cationic sub-lattice, in which octahedral sites are stabilized by size-depen...

Summary: | Copper selenide is super-ionic only at high temperatures. Here, the authors discover room temperature super-ionic behaviour in ultrasmall clusters of Cu2Se—but not in its larger or bulk forms—owing to an unusual liquid-like cationic sub-lattice, in which octahedral sites are stabilized by size-dependent compressive strain. |
