The Debye model is a method developed by Peter Debye in 1912 [ 7] for estimating the phonon contribution to the specific heat (heat capacity) in a solid [ 1]. This model correctly explains the low temperature dependence of the heat capacity, which is proportional to T3 and also recovers the Dulong-Petit law at high temperatures. haims bbq
