The electronic device comprises an organic semiconductor material in a monodomain structure on a substrate. Said semiconductor material is preferably part of a transistor, wherein the monodomain extends on the channel, i.e. from a source to a drain electrode. The material comprises a mesogenic unit with spacer groups and end groups. The end groups are preferably reactive, i.e. dienes, acrylates, oxetanes or the like. The mesogenic unit contains a central oligothiophenyl-group, rigid spacer groups, particularly acetylenes, and additional groups, for instance thiophenyl or phenyl.

摘要:
A magnetic actuator system which includes a case (10) and a spindle (22) which extends through the case comprising a magnetizable material such as iron. The actuator further includes a pair of permanent magnet assemblies (14, 16) positioned fixedly within the casing with a longitudinal space there between, wherein the permanent magnet assemblies comprise an alternating plurality of north pole/south magnet sections (18) which extend longitudinally or circumferentially of the actuator. The actuator further includes a coil winding (24) which surrounds the spindle, positioned between the two permanent magnet assemblies. Magnetic pole assemblies (28, 30) attached to the spindle are positioned within the volume encompassed by the permanent magnet assemblies, such that an alternating drive signal produces an oscillating action of the spindle of desired frequency and amplitude.
