Abstract

Photoconduction study of quasi-1D conductors allows to distinguish between the single-particle and collective {\it linear} conduction, investigate the effect of screening on collective transport and obtain interesting new details of the electronic energy structure of pure and doped CDW conductors. Here we present results of photoconduction study in quasi-1D conductors o-TaS$_3$, K$_{0.3}$MoO$_3$, and NbS$_3$(I).
