- 論文の詳細を見る
The mobility of pentacene-based organic field-effect transistors (OFETs) fabricated on natural mica substrates has been highly improved using poly(methyl methacrylate) (PMMA) or octadecyltrimethoxysillane (OTMS) as a buffer layer between the mica dielectric and the pentacene active layer. The field-effect mobility increased from $2.4\times 10^{-3}$ to 0.14 or 0.31 cm2$\cdot$V-1$\cdot$s-1 by inserting the PMMA or OTMS buffer layer, respectively. The suppression of the unfavorable effect of potassium ions using the OTMS buffer layer confirmed the feasibility of using natural mica as a transparent gate dielectric of OFETs.
