Claim:
1. A composition of matter comprising a bundle of polymer fibers, wherein: (a) the polymer fibers are formed from conjugated polymers comprising a plurality donor and acceptor units; (b) the conjugated polymers are disposed in the fibers such that longitudinal axes of the conjugated polymers within the polymer fibers are substantially aligned along longitudinal axes of the polymer fibers; (c) a plurality of the polymer fibers in the bundle are disposed in a non random orientation such that the plurality of polymer fibers are directionally aligned; and (d) the plurality of directionally aligned polymer fibers are adapted to transport charge between source and drain electrodes in a field effect transistor such that the field effect saturation mobility of the plurality of directionally aligned polymer fibers in the field effect transistor is at least 10 cm
