Abstract

A voltage instability in the charge-density-wave conducting state of Rb0.3MoO3 and K0.3MoO3 is investigated. Voltage pulses are created at a well-defined location within the sample and propagate along the crystal. With increasing field the pulse creation frequency increases, and the pulses merge into a narrow-band oscillation. The field and temperature dependence of characteristic quantities is given. The results are interpreted in the framework of a moving charge-density-wave dislocation model by Lee and Rice. The consequences on the origin of narrow-band voltage noise are also discussed.
