RIBEIRO FILHO, A.; NASCIMENTO, E. M. do and VASCONCELOS, D. S. de. Eigenmode frequencies calculations in the charge-density-wave states of 2H-TaSe2 . Braz. J. Phys. [online]. 1998, vol.28, n.3, pp. 241-249. ISSN 1678-4448. http://dx.doi.org/10.1590/S0103-97331998000300009.
We have performed some calculations involving two eigenmode frequencies of 2H - TaSe2. We have obtained a good comparison with some well established Raman scattering data for the commensurate and incommensurate charge-density-wave phases in this compound. We outline an approximated method to compute the determinantal equation.
