Impact of crystal structure on the lattice thermal conductivity of the IV-VI chalcogenides We present a detailed comparative study of the lattice thermal conductivity κlatt of ten reported phases of the IV-VI chalcogenides GeSe, GeTe, SnSe and SnTe, calculated within the single-mode relaxation-time approximation based on third-order interatomic force constants.

Thermoelectric properties of Pnma and R3m GeS and GeSe With ∼60 % of global energy lost as heat, technologies such as thermoelectric generators (TEGs) are an important route to enhancing the efficiency of energy-intensive processes. Optimising ther- moelectric (TE) materials requires balancing a set of interdependent physical properties to meet efficiency, cost and sustainability requirements, and is a complex materials-design challenge.
