Picosecond Photoconductivity in Trans-Polyacetylene.
Abstract
Fast transient photoconductivity measurements of trans-polyacetylene as a function of temperature and photon energy indicate a relatively high quantum efficiency for the photoproduction of mobile, charged, nonlinear excitations. Excitation by a 20ps pulse at 590nm with 10 to the 15th power photons/sq cm results in a transient photoconductivity of approx. 0.3 S/cm (at 50 ps) with time scale for decay similar to that measured in picosecond photoinduced absorption experiments. The temperature independence of the fast photoconductivity is interpreted in terms of the photoproduction of hot soliton excitations.
