Photo-Induced Charge Carrier Generation in Thin Film Polydiacetylene Single Crystals.

摘要

Investigation of the angular dependence of incident light polarization on the photocurrent in thin film polydiacetylene single crystals with different side groups is reported. These experiments, show for the first time that charge carrier generation in these quasi-one-dimensional semiconductors is very sensitive to the nature and organization of the side groups. Models explaining photocarrier generation in such materials need to be reevaluated in light of these experimental results.
