Highly oriented layers of organic semiconductors: hexa-benzocoronene (p-type) andperylene derivative (n-type) were obtained by the zone-casting technique – a one step method of producing highly aligned layers of solution processible organic materials with no need of use of any preoriented surface. Orientation was confirmed by X-ray diffraction, optical and atomic force microscopy observations and charge carrier transport anisotropy. First field effect transistor based on the zone-cast layer is presented.
