Charge Mobility in Polymer Systems
A.R. Tameev
Recently performed experimental studies on charge carrier transport in various polymer systems are reviewed briefly. A key transport parameter, drift mobility, measured using conventional time-of-flight techniques is considered. Particular attention is given to conjugated (polyfluorenes, polyphenylene-vinylenes), non-conjugated (aromatic polyimides) polymers and molecularly doped polymers (nanostructures of J -aggregated dyes). The correlated disorder model appears to give a better fit of the data providing energetic features of the transport molecules are taken into account.
