Abstract
The Charge Density Wave (CDW) in the layered compound 1T-TaSe2 at low temperatures has a commensurate phase which causes superlattice points to appear in the Brillouin zone of the undistorted phase. The phonon frequency distribution of this system for both the normal and the Commensurate Charge Density Wave (CCDW) phases have been worked out theoretically using the Born-von Karmann formalism. With these results the thermal properties such as specific heat capacity, Debye-Waller factor and thermal conductivity have been worked out and are compared with the available experimental results.
