Dimer rattling mode induced low thermal conductivity in an excellent acoustic conductor

Dimer rattling mode induced low thermal conductivity in an excellent acoustic conductor

CuP2 has a puzzling thermal transport behavior, with low thermal conductivity but quite large mean sound speeds. Here, the authors conduct a systematical study of the atomic structure and lattice dynamics of CuP2 to reveal the origin, finding a dimer rattling behavior.
