PROJECT TITLE :
Single Mesowire Transistor From Perylene Tetracarboxylic Diimide
We have recently fabricated new nano/mesowires of perylene tetracarboxylic diimide (PTCDI) without side chains by self-assembling them from a gas phase. In this letter, we discuss a single PTCDI mesowire transistor that was successfully fabricated, characterized, and modeled. This organic n-channel field effect transistor shows good output and transfer characteristics. Our transistor model includes the Poole–Frenkel electric field dependence of charge carrier mobility in organic materials and fits all experimental output characteristics of the transistor. The zero-field charge carrier mobility of the PTCDI mesowire is found to be 0.72 cm $^2$/(V·s). The experimental results are promising for the further development of single nanowire transistors and advancement of organic nanoelectronics.
