Ab initio study of K3Cu3P

Investigations on the thermoelectric and thermodynamic properties of quaternary coinage metal HgSBr

“…A B/G value exceeding 1.75 indicates brittleness, while values below 1.75 suggest ductility. For pure covalent and ionic materials, Poisson's ratio (n) is typically around 0.1–0.25 and 0.25–0.5 [ [54] , [55] , [56] ], respectively. Therefore, CuHgSBr can be considered ductile and strongly ionic character.…”
