Field Effect Studies on Rubrene and Impurities of Rubrene

contaminate rubrene have been identified and their structures determined. Single crystals of rubrene show
excellent crystallinity and very small rocking curve width. Field effect transistors based on pure rubrene
single crystals with colloidal graphite electrodes and Parylene as a dielectric demonstrate a maximal
mobility of 13 cm2/Vs with strong anisotropy. The mobility increases very slightly with cooling, but
decreases significantly at low temperatures.
