Eigenmode frequencies calculations in the charge-density-wave states of 2H - TaSe2·

Abstract

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. Subject Classification: 64.70.Rh; 77.80.Bh; S1.63.
