Abstract
Pulsed photoconductivity measurements in polyacetylene and ß-carotene (an oligomer with eleven conjugated double bonds) are reported. Since both polyacetylene and ß-carotene show light-induced conductivity, we have studied the lifetime of photoexcited carriers in these two systems. Some measurements were done in the picosecond regime to study the carrier motion before trapping,as well as in the micro- and millisecond regime to investigate the relaxation of carriers hopping between localized states. The experimental configuration is pointed out,and some of the difficulties connected with such experiments are discussed.
