Lattice thermal conductivity strongly affects the applications of materials related to thermal functionality, such as thermal management, thermal barrier coatings and thermoelectrics. In order to understand lattice thermal conductivity more quantitatively and in a time- and cost-effective way, many researchers have devoted their efforts and developed a few physical models using approximated phonon dispersions over the past century.
