Organic single crystal field-effect transistors of a soluble anthradithiophene

We use single crystals (grown by physical vapor transport) of a soluble oligomer to obtain a better understanding of the intrinsic properties, limitations and potential of these materials. Single crystals are well-suited for studies exploring the effects of chemical structure and molecular packing separate from solvent effects. We report on the fabrication of organic field-effect transistors from 2,8-difluoro-5,11-bis(triethylsilylethynyl) anthradithiophene (diF-TESADT) single crystals. Gen- eral characteristics of these devices are high mobilities (6 cm2/(Vs)), large current on/off ratios (Ion/Ioff = 10^8), small subthreshold slopes (S = 1 V/dec) and extremely small hysteresis in the current-voltage characteristics.
