| description | Controlling the flow of thermal energy is crucial to numerous applications ranging from microelectronic devices to energy storage and energy conversion devices. Here, we report ultralow lattice thermal conductivities of solution-synthesized, single-crystalline all-inorganic halide perovskite nanowires composed of CsPbI[subscript 3] (0.45 ± 0.05 W·m[superscript −1] ·K[superscript −1]), CsPbBr[subscript 3] (0.42 ± 0.04 W·m[superscript −1] ·K [superscript −1]), and CsSnI[superscript 3] (0.38 ± 0.04 W·m[superscript −1] ·K[superscript −1]). We attribute this ultralow thermal conductivity to the cluster rattling mechanism, wherein strong optical–acoustic phonon scatterings are driven by a mixture of 0D/1D/2D collective motions. Remarkably, CsSnI[superscript 3] possesses a rare combination of ultralow thermal conductivity, high electrical conductivity (282 S·cm[superscript −1]), and high hole mobility (394 cm[superscript 2] ·V[superscript −1] ·s[superscript −1]). The unique thermal transport properties in all-inorganic halide perovskites hold promise for diverse applications such as phononic and thermoelectric devices. Furthermore, the insights obtained from this work suggest an opportunity to discover low thermal conductivity materials among unexplored inorganic crystals beyond caged and layered structures.
