Three-dimensional order of charge-density waves in layered compounds
Bulaevskii L.N., Khomskii D.I.
The period of the charge-density waves in a direction perpendicular to the layers is determined for layered compounds of the 2H-TaSe2 and lT-TaSe2 type on the basis of the phenomenological Landau theory. The predictions of the theory agree with the experimental data.
