Thermoelectric Properties of All-Inorganic Halide Perovskite Nanowires

ORAL

Abstract

Controlling the flow of thermal energy is crucial to numerous applications ranging from microelectronic devices to energy storage and energy conversion devices. I will present experimental ultralow lattice thermal conductivities of solution-synthesized, single-crystalline all-inorganic halide perovskite nanowires composed of CsPbI3, CsPbBr3, and CsSnI3. I will also discuss mechanisms behind ultralow thermal conductivitiy values of all-inorganic halide perovskites. Further, we found that CsSnI3 possesses a rare combination of ultralow thermal conductivity and high electrical conductivity. CsSnI3 is a promsing candidate for thermoelectric applications.
