Origin of anisotropic thermal transport in CsPbBr3

We reveal the specific structural and bonding features that result in anisotropic thermal transport for CsPbBr3 by directional single-crystal measurements and elucidate the bases for the low Debye temperature and speed of sound. This work enhances the research on perovskites and reveals the structur...

Description
Summary:We reveal the specific structural and bonding features that result in anisotropic thermal transport for CsPbBr3 by directional single-crystal measurements and elucidate the bases for the low Debye temperature and speed of sound. This work enhances the research on perovskites and reveals the structural features governing the thermal properties.
