Abstract
- The uniaxial zero thermal expansion (ZTE) in distorted Prussian blue analogue (PBA) RbCuCo(CN)<subscript>6</subscript> is reproduced by employing first-principles calculations, which agrees well with the experimental data. Also, the zero linear compressibility (ZLC) behavior in RbCuCo(CN)<subscript>6</subscript> can be found. The special Jahn–Teller distortion introduced by Cu<superscript>2+</superscript> in RbCuCo(CN)<subscript>6</subscript> is noticed by investigating the change of the local structure with temperature and hydrostatic pressure. The lattice thermal conductivity (LTC) and phonon group velocity of RbCuCo(CN)<subscript>6</subscript> are studied, where the LTC and phonon group velocity are significantly anisotropic. Especially, RbCuCo(CN)<subscript>6</subscript> exhibits a quite low LTC, and its c-axis shows a characteristic of glasslike LTC at low temperatures. Our work facilitates a deep understanding of the coexistence mechanisms of uniaxial ZTE and ZLC properties in RbCuCo(CN)<subscript>6</subscript>. [ABSTRACT FROM AUTHOR]
