スメクチックE相薄膜を活性層とする室温動作・高移動度の有機トランジスタの特性評価

抄録

We have developed a new dialkyl Ph-BTBT derivative, i.e., 4-Ph-BTBT-10, which exhibits smectic E phase at a wide temperature range including room temperatures, investigated its carrier transport property by time of flight technique , and fabricated field effect transistors (FETs). The FET show s high mobility of 0.4 cm²/Vs, which is the highest mobility in FETs fabricated with liquid crystalline thin films at room temperature several reported.
