Charge-Density-Wave Transport in Quasi - One-Dimensional Conductors
Abstract
dc:descriptionA detailed experimental study of the remarkable collective-transport properties of charge-density-wave (CDW) conductors is presented. Measurements of current oscillations observed in response to applied dc voltages and of mode-locking phenomena observed in response to combined ac and dc voltages indicate a nearly complete analogy with similar effects observed in Josephson junctions. Even though these effects result from CDW interaction with randomly-distributed impurities, they are extraordinarily clean and beautiful: current-oscillation spectra with 23 harmonics and spectral widths of one part in 30,000 and literally hundreds of subharmonic mode-locked features in the dc I-V characteristic are observed. However, crystal defects other than impurities can significantly degrade the measured properties, and play a determining role in the generation of broad-bandwidth noise.
