Paper Abstract

The anisotropy of the picosecond photoconductive response of trans-polyacetylene was measured for both above- (0.53?m) and below-gap (1.06?m) excitation. The anisotropy for below-gap excitation remain constant at a value of 2.4, independent of the laser intensity, while the anisoiropy for above-gap excitation decreased from a value of 7.4 to 4.5 as the intensity increased. In addition, the picosecond photocurrent was greatest for below-gap excitation. These results demonstrate the photoproduction of nonlinear charge carriers (solitons and polarons ) atenergies below the principle interband absorption edge.
