This work summarizes the results of series of works devoted to the study of the mechanisms of low-temperature conduction and photoconduction in the Peierls conductor orthorhombic TaS3 (o-TaS3). We used the tools we discovered to change the relationship between the single-particle and collective components of low-temperature photoconduction and conduction in o-TaS3 – illumination and uniaxial stretching of the sample. Using them, we were able to separate single-particle and collective contributions and show that the collective contribution dominates both low-temperature conduction (T ≲ 100 K) and low-temperature photoconduction (T ≲ 45 K). In addition, the discovered analogy between the influence of illumination and stretching on low-temperature conduction and photoconduction made it possible to establish the dimension of charge density wave (CDW) pinning in samples of different cross-sections at low temperatures. It was found that for all samples, including bulk ones, one-dimensional pinning is observed at temperatures T < 40 K, and it also has a collective character.
