Complete miscibility amongst AV${}_3$Sb${}_5$ kagome superconductors: design of mixed A-site AV${}_3$Sb${}_5$ (A: K, Rb, Cs) alloys

Brenden R. Ortiz, Andrea N. Capa Salinas, Miles J. Knudtson +3

In this work we explore the chemical-property phase diagram of the AV${}_3$Sb${}_5$ family through A-site alloying. We demonstrate full miscibility of the alkali-site, highlighting tha…
