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

A solid with larger sound speeds usually exhibits higher lattice thermal conductivity. Here, we report an exception that CuP(2) has a quite large mean sound speed of 4155 m s(−1), comparable to GaAs, but single crystals show very low lattice thermal conductivity of about 4 W m(−1) K(−1) at room temp...
