Abstract
We investigate the relation between rf-induced Shapiro steps and current oscillations in the charge-density-wave (CDW) state of . The Shapiro step magnitude is independent of the oscillation amplitude, and a rich spectrum of harmonic and subharmonic steps is observed. These results provide evidence for phase homogenization or excitation of internal modes of the CDW condensate.
