Fig. 1: Lattice thermal conductivity (κL) at room temperature varying with number mismatch between cations and anions (δ) in ternary Cu- and Ag-based chalcogenides.

From: Number mismatch between cations and anions as an indicator for low lattice thermal conductivity in chalcogenides

The red line is a guide to the eyes. The green square is Cu4Sn7S16, which is used for the case study. Cu2Sn4S9 and Cu4SnS4 (red circle) are the screened low κL materials based on proposed number mismatch between cations and anions. The raw data and the source for each material can be found in Supplementary Table 1.
