Abstract
The specific heat and entropy of (wurtzite) GaN are not well known experimentally. The literature values for Cp (T > 298 K) are based on a fit to an analytic function. The parameters include Cp (298 K) and the melting temperature Tm, both of which were poorly known when the parameters were first determined. The value of Cp (298 K) disagrees with the data measured in the range 5-305 K. Our first-principles calculations allow the values of the parameters to be established and lead to a more accurate prediction of specific heat and entropy of GaN.
