Abstract
The layered charge-density-wave (CDW) material was studied by angle-resolved photoelectron spectroscopy. We present the first experimental mapping of the Fermi surface (FS) portions involved in the CDW transition. From this and additional data on the conduction band dispersion near the Fermi level we conclude that the CDW instability in this material is driven by FS nesting and not by saddle point singularities.
