Thermoelectric copper selenides are highly attractive owing to not only their constituent
nontoxic, abundant elements but also their ultralow liquid-like lattice thermal conductivity …

The lead-free halide double perovskite class of materials offers a promising venue for
resolving issues related to toxicity of Pb and long-term stability of the lead-containing halide …

Materials based on cubic tetrahedrites (Cu 12 Sb 4 S 13) are useful thermoelectrics with

Thermoelectric materials are capable of converting waste heat into electricity. Half-Heusler
materials, as one of the promising candidates for thermoelectrics, have a relatively low figure …

Thermal conductivity (⁠ κ L⁠) plays a critical role in thermal management applications.
Usually, crystals with simpler structures exhibit higher κ L due to fewer phonon scatterings …
