Abstract

We investigate organic and inorganic crystals with a quasi-one-dimensional electronic structure. It is well established that these systems are able to undergo a Peierls transition. Below the transition temperature the electrons increasingly condensate to a charge density wave. The charge density wave is able to contribute to the charge transport above a threshold electrical field, leading to nonlinear conductivity. The motion of the condensate is accompanied by narrow-band noise and broad-band noise. The metastability of the charge density wave defects leads to hysteresis and memory effects. Self-organized criticality and switching oscillations have been found near the threshold electrical field. The observed complex behavior in the time domain makes it plausible to expect charge density wave systems also to organize in space.
