Abstract

The results of steady state photoconductivity experiments on cis- and trans-(CH)x are interpreted in terms of charged solitons, photogenerated either directly (threshold hv = 4Δ/π) or indirectly through coupling of the lattice to electron-hole pair excitations (hv ≥ 2Δ). The transient photocurrent, after laser pulse excitation, decays as a power law, I(t) ≅ t-0.6, suggesting dispersive transport of the photogenerated carriers.
