	1	Largely Suppressed Magneto-Thermal Conductivity and Enhanced Magneto-Thermoelectric Properties in PtSn_(4)显示文摘Highly conductive topological semimetals with exotic electronic structures offer fertile ground for the investigation of the electrical and thermal transport behavior of quasiparticles.Here,we find that the layer-structured Dirac semimetal PtSn4 exhibits a largely suppressed thermal conductivity under a magnetic field.At low temperatures,a dramatic decrease in the thermal conductivity of PtSn4 by more than two orders of magnitude is obtained at 9 T.Moreover,PtSn_(4)shows both strong longitudinal and transverse thermoelectric responses under a magnetic field.Large power factor and Nernst power factor of approximately 80-100μW·cm^(-1)·K^(-2)are obtained around 15K in various magnetic fields.As a result,the thermoelectric figure of merit zT is strongly enhanced by more than 30 times,compared to that without a magnetic field.This work provides a paradigm for the decoupling of the electron and hole transport behavior of highly conductive topological semimetals and is helpful for developing topological semimetals for thermoelectric energy conversion.
