Abstract
We report on the fabrication and characterization of single-crystal field-effect transistors (FETs) based on 2,6-diphenylbenzo[1,2-b:4,5-b′]diselenophene (DPh-BDSe). These organic field-effect transistors (OFETs) function as p-channel accumulation-mode devices. At room temperature, for the best devices, the threshold voltage is less than -7 V and charge carrier mobility is nearly gate bias independent, ranging from 1 to 1.5 cm2/(V s) depending on the source-drain bias. Mobility is increased slightly by cooling below room temperature and decreases below 280 K.
