中文摘要	organic heterojunction transistors (ohjts) based on 5,5'"-bis(naphtha-2-yl)-2,2':5",2"-quaterthiophene (nat(4))/copper-hexadecafluoro-phthalocyanine (f(16)cupc) heterojunction were fabricated in single-sandwich and sandwich configurations, respectively. all the devices operated in depletion-accumulation (normally-on) mode. high field-effect mobility of 0.35 cm(2)/vs was obtained for all devices, which was higher than that, 0.20 cm(2)/vs of the devices with nat(4) as active layer. the on/off ratio of 1 x 10(5) was obtained for ohjts with single-sandwich configuration, which is three orders of magnitude higher than that of ohjts with sandwich configuration. compared with ohjts with sandwich configuration, the higher on/off ratio was mainly determined by the lower off state current in ohjts with single-sandwich configuration. in ohjts with single-sandwich configuration, the well-type shield effect of the source and drain electrodes caused a very narrow empty region in f(16)cupc film, which is responsible for the lower off state current. crown copyright (c) 2011 published by elsevier ltd. all rights reserved.
