Evidence Details

Equipment evidence

Subsequently, the PTFE vessel was sealed in a polyetheretherketone autoclave, placed in a microwave chemical synthesizer (XiangHu Technologies XH-8000Plus), heated to 473 K within 40 min, remained at 473 K for 60 min under an autogenous pressure of ≈1.60 MPa.

Source evidence

... lower lattice thermal conductivity (e.g., 0.48 W m−1 K−1 at 721 K) ...

Source evidence

A decent maximum zT of 0.50 is obtained in KCu7S4 at 721 K along the “⊥” direction ... This zT represents a ≈100% enhancement compared to the one obtained along the “||” direction.
