The debye frequency

  1. Feb 27, 2006 #1
    in a crystal, when proving the debye frequency, why is the existence of longitudinal lattice ignored? why is there longitudinal lattice in the first place???

    Can you provide a reference? I don't recall "proving the debye freq", actually I'm not sure what that statement means.

    What is a longitudinal lattice ?

    Are you saying that Debye's calculation ignores longitudinal modes ? That is not true.

    That's not enough. You must provide the exact quote from Reed-Hill.
