Fermi-surface analysis of a quasi-two-dimensional monophosphate tungsten bronze

The P4W8O32 compound is a member of the low-dimensional monophosphate tungsten bronzes family whose reduced dimensionality induces electronic instabilities such as charge-density waves (CDWs). We report here the direct mapping of the Fermi surface (FS) of this compound at room temperature using sync...
