[ 8] Low Temperature Limit At very low temperature where T ≪ TD, only long wavelength acoustic modes are thermally excited. These are just the modes that can be treated as elastic continuum with macroscopic elastic constants.

Webwe computed the specific heat of UNCD as a function of temperature from the vibrational spectra. We find that the specific heat of UNCD shows enhancements of approximately 20% over that of single-crystal diamond at 300 K. The excess specific heat in UNCD in comparison to single-crystal diamond is found to be maximum at approximately 350 K. WebThe specific heat of diamond at 500° is about 0.4 cal./g. °C. and this decreases to only 0.0025 cal./g. °C. at 90° K. The average specific heat over this temperature range is about 0.23 cal./g. °C. and the sensible heat is, therefore, 160 cal. per gram. This is about 105 times greater than the heat of adsorption.
