Abstract
Photoinduced current has been measured in the range 0.5–3.4 eV in trans-polyacetylene of about 100 µm thickness. The typical photoinduced current spectrum shows a peak at 1.4 eV below the interband absorption edge and a sharp decrease below 0.7 eV. By observing the dependence of photoinduced current spectra on sample degradation and compensation with ammonia, it has been concluded that there exist four distinct spectral regions. Photoinduced current in one of them, the lowest energy region, has been ascribed to the bolometric effects, while those in the other regions are genuine photoconductivity.
