Debye specific heat

Debye specific heat

[də′bī spə‚sif·ik ′hēt]
(solid-state physics)
The specific heat of a solid under the assumption that the energy of the lattice arises entirely from acoustic lattice vibration modes which all have the same sound velocity, and that frequencies are cut off at a maximum such that the total number of modes equals the number of degrees of freedom of the solid.
