摘要
BiAgSeS shows intrinsically low thermal conductivity in the temperature range from 300 K (∼0.46 W m-1 K-1) to 823 K (∼0.29 W m-1 K-1). Low thermal conductivity coupling with enhanced electrical transport properties achieved through partially substituting S2- by Cl- leads to a high ZT of ∼1.0 at 823 K for BiAgSeS0.97Cl0.03, indicating that the BiAgSeS system is promising for thermoelectric power generation applications.
