Field-effect transistors (FETs) consisting of vapor-deposited thin-film of dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT) as an active layer on silanized Si/SiO2 substrates were fabricated and evaluated. Depending on the length of alkyl groups in silanization reagents, FET characteristics of the devices were affected: with octadecyltrichlorosilane (C18-OTS), devices showing superior FET characteristics up to FET mobility of 3.1 cm2 V-1 s-1 were obtained.
