 Many low-dimensional solids have anisotropic Fermi surfaces that have prominent nesting vectors.Well-known examples include layered materials like NbSe3, TaSe2 and K0.3MoO3 (a Chevrel phase) and quasi-1D organic conductors like TMTSF or TTF-TCNQ.CDWs are also common at the surface of solids where they are more commonly called surface reconstructions or even dimerization.
