The efficiency of a thermoelectric material is measured by the figure of merit ZT, which is inversely proportional to the thermal conductivity. Superlattice structures often have a reduced thermal conductivity because of the introduction of interface scattering and, therefore, improved performance.

## Abstract Molecular dynamics simulation using the new fit of the empirical Tersoff Potential is applied to study the thermal properties of ZnSe at and below the room temperature. The resulting diffusivity and thermal conductivity are compared with the photoacoustic measurements on the grown ZnSe
