摘要

In the discussion and analysis of thermal properties (e.g.heat capacity, thermal conductivity) the Debye approximation is typically used to describe the collective behavior of lattice vibrations (phonons)in solid materials.Because the Debye model has been successful in explaining many properties of materials, particularly in contrast to the non-dispersive model considered by Einstein, the Debye modelis often the starting point of introductory textbooks in solid state physics.
