Abstract
We fabricated copper phthalocyanine (CuPc) thin-film field-effect transistors (FETs) on a rubbed flexible polyethersulfone (PES) substrate. Rubbing the PES film induced a unidirectional orientation of CuPc crystallites, which were oriented perpendicular to the rubbing direction. Favorable conditions for fabricating a CuPc FET were determined after fabricating CuPc FETs of two different types and evaluating their output performance. Well-aligned CuPc crystallites along the direction connecting source and drain electrodes can play an important role in improving the output performance of the fabricated FETs.
