Web20 sep. 2024 · Abstract. Lattice thermal conductivity (κ L) is one of the most fundamental properties of solids.The acoustic–elastic-wave assumption, proposed by Debye (Debye P. Ann Phys 1912; 344: 789–839), has led to linear phonon dispersion being the most common approximation for understanding phonon transport over the past century.Such an … Web3 mei 2024 · Materials with a high thermoelectric efficiency have a relatively low thermal conductivity, which is closely related to their chemical bonding and lattice dynamics. Therefore, it is essential to investigate the lattice dynamics of materials to further improve their thermoelectric efficiency.
