Abstract

Single-crystal field effect transistors of the organic semiconductor dithiophene-tetrathiafulvalene (DT-TTF) were prepared by drop casting. Long, thin crystals connected two microfabricated gold electrodes, and a silicon substrate was used as a back gate. The highest hole mobility observed was 1.4 cm2/Vs, which is the highest reported for an organic semiconductor not based on pentacene. A high ON/OFF ratio of at least 7 x 105 was obtained for this device.

摘要

通过滴铸法制备了有机半导体二噻吩 - 四硫富瓦烯（DT - TTF）的单晶场效应晶体管。长而细的晶体连接着两个微加工的金电极，并使用硅衬底作为背栅。观察到的最高空穴迁移率为1.4 cm²/Vs，这是未基于并五苯的有机半导体所报道的最高值。该器件获得了至少7×10⁵的高开/关比。
