Abstract
The electron mobility, hot electron effects, and the role of polarons are studied theoretically in a one-dimensional semiconductor. A particular semiconducting polymer, the bis(P-toluene sulphonate) ester of 2,4-hexadiyne-1,6-diol, PDATS, is used as an example. Interaction with acoustic phonons alone is considered in the deformation potential approximation. The dependence of drift velocity on electric field is qualitatively different depending upon whether the phonons are one-dimensional (as for one isolated chain) or three-dimensional (as for a chain in a medium). And in both cases the results are qualitatively different from the established results for a three-dimensional semiconductor.Keywords
