Abstract

We report the effect of organic solvents for spin coating dialkyl BTBT on the mobility of top-gate organic FETs. Top-gate Ca-BTBT and C12-BTBT FETs processed using non-halogen solvents under optimized conditions exhiba high average mobilities of 5.2 and 7.8 cm2A/s, respectively. The maximum mobility of ~10 cmWs is achieved.
